This implements a new `FocusSerial` command: `plugins`. The `plugins` command
will reply back with a list of plugins enabled in the firmware. The list is not
exhaustive, only plugins that opt-in to this mechanism will be listed. It is
opt-in, because for a lot of plugins, having them listed isn't useful in a
practical sense.
The goal with this feature is to allow Chrysalis to detect plugins that would
affect what keys it offers, or which additional settings it displays, and do so
in a consistent way. This is why IdleLEDs has an `onNameQuery` handler too, even
though it can be detected otherwise: for consistency.

- `beforeEachCycle()`: Called once, at the beginning of each cycle of the main loop. This is similar to the old "loop hook" with its `post_clear` argument set to false. Takes no arguments, must return `kaleidoscope::EventHandlerResult::OK`.
- `onKeyswitchEvent`: Called for every non-idle key event. This replaces the old "event handler hook". It takes a key reference, a key address, and a key state. The key reference can be updated to change the key being processed, so that any plugin that processes it further, will see the updated key. Can return `kaleidoscope::EventHandlerResult::OK` to let other plugins process the event further, or `kaleidoscope::EventHandlerResult::EVENT_CONSUMED` to stop processing.
- `onFocusEvent`: Used to implement [bi-directional communication](#bidirectional-communication-for-plugins). This is called whenever the firmware receives a command from the host. The only argument is the command name. Can return `kaleidoscope::EventHandlerResult::OK` to let other plugins process the event further, or `kaleidoscope::EventHandlerResult::EVENT_CONSUMED` to stop processing.
- `onNameQuery`: Used by the [Focus](#bidirecional-communication-for-plugins) plugin, when replying to a `plugins` command. Should either send the plugin name, or not be implemented at all, if the host knowing about the plugin isn't important.
- `beforeReportingState`: Called without arguments, just before sending the keyboard and mouse reports to the host. Must return `kaleidoscope::EventHandlerResult::OK`.
- `afterEachCycle`: Called without arguments at the very end of each cycle. This is the replacement for the "loop hook" with its `post_clear` argument set.

### Repository rearchitecture
To improve build times and to better highlight Kaleidoscope's many plugins, plugins have been move into directories inside the Kaleidoscope directory.
To improve build times and to better highlight Kaleidoscope's many plugins, plugins have been move into directories inside the Kaleidoscope directory.
The "breaking change" part of this is that git checkouts of Kaleidoscope are no longer directly compatible with the Arduino IDE, since plugins aren't in a directory the IDE looks in. They are, of course, visible to tools using our commandline build infrastructure / Makefiles.

Both of them take a variable number of arguments, of almost any type: all built-in types can be sent, `cRGB`, `Key` and `bool` too in addition. For colors, `.send()` will write them as an `R G B` sequence; `Key` objects will be sent as the raw 16-bit keycode; and `bool` will be sent as either the string `true`, or `false`.
### `.sendName(F("..."))`
To be used with the `onNameQuery()` hook, this sends the plugin name given,
followed by a newline, and returns `EventHandlerResult::OK`, so that
`onNameQuery()` hooks can be implemented in a single line with the help of this
function.
### `.read(variable)`
Depending on the type of the variable passed by reference, reads a 8 or 16-bit unsigned integer, a `Key`, or a `cRGB` color from the wire, into the variable passed as the argument.
