Added hotkeys. Updated readme:

Hotkeys:

You can enable hotkeys for the convertpins and 'convertpins ignorelocaldupes' commands.
To enable, adjust the Hotkeys section in the config accordingly. A list of
valid strings can be found here: https://docs.unity3d.com/ScriptReference/KeyCode.html.
Leave empty for no hotkey (default).

Example:

## Hotkey to run /convertpins
# Setting type: String
# Default value: 
KeyConvertAll = F10

## Hotkey to run /convertpins ignorelocaldupes
# Setting type: String
# Default value: 
KeyConvertIgnoreDupes = F11
