Fix SSH to tablet

At some point the tablets were updated and the default host key
algorithm became ed25519 where it had previously been rsa. The default
list of host key algorithms allowed by the Go SSH client does not
include ed25519 which prevented the client from connecting.

A solution some people used was to SSH into the tablet using the
operating system's client configuration that accepted the tablet's new
key. From there they would generate a new rsa key on the tablet which
then enabled remouseable to connect. This patch prevents the need for
creating a new key to connect, though that may be an effective solution
should the default key types change again in a way that breaks
remouseable.

Add better OSX support

This release adds support for the OSX mouse drag event which is expected by certain applications being used on Apple devices such as Onenote.

Added windows build and build instructions

Add windows build instructions

Embedd robotgo

This release introduces an embedded version of robotgo that has been stripped down to only the portions needed for mouse control and screen size detection. This is an attempt to make the binaries more portable by removing most of the dependencies other than those that come with the host system by default.

Initial release

Single monitor support for Linux workstations.
Unit tested and expected to work for OSX/Windows but not yet tried with an actual device.
