feat(tcp): add listener + export socket schema

This commit adds a TCP listener that can be optionally exposed on a port
provided by the user using the --tcp-port flag. If the flag is not
provided, the TCP listener will not be started.

Client state is tracked using the connecting address, and clients are
purged if they send unrecognised messages.

A JSON Schema of the SocketMessage enum can be exported via komorebic
and be used to generate type definitions in various programming
languages.

This commit also makes some improvements to the handling of 'komorebic
start'.

The previous backoff approach was not working as once the Windows API
denies access to the process for any call, no amount of retries with the
same process id will result in approval.

Therefore, 'komorebic start' now checks if the process has been started,
and if it hasn't (ie. it has errored out because of an access denied
error), it will continue to restart the process until all the komorebi
startup calls to the Windows API succeed.

### Communication over TCP
A TCP listener can optionally be exposed on a port of your choosing with the `--tcp-port=N` flag. If this flag is not
provided to `komorebi` or `komorebic start`, no TCP listener will be created.
Once created, your client may send
any [SocketMessage](https://github.com/LGUG2Z/komorebi/blob/master/komorebi-core/src/lib.rs#L37) to `komorebi` in the
same way that `komorebic` would.
This can be used if you would like to create your own alternative to `komorebic` which incorporates scripting and
various middleware layers, and similarly it can be used if you would like to integrate `komorebi` with
a [custom input handler](https://github.com/LGUG2Z/komorebi/issues/176#issue-1302643961).
If a client sends an unrecognized message, it will be disconnected and have to reconnect before trying to communicate
again.
### Socket Message Schema
A [JSON Schema](https://json-schema.org/) of socket messages used to send instructions to `komorebi` can be generated
with the `komorebic socket-schema` command. The output of this command can be redirected to the clipboard or a file,
which can be used with services such as [Quicktype](https://app.quicktype.io/) to generate type definitions in different
programming languages.
