Missing anti-deadzone setting

[Jezorko]

Currently only deadzone configuration is supported.

This would be a very useful feature for games that have hardcoded deadzones (e.g. SnowRunner).

I see there is some logic already in the code, but the UI configuration does not have a field to set the anti-deadzone values.

I added the anti-deadzone setting and created a PR: https://github.com/csutorasa/XOutput/pull/593

Here's a compiled .exe with working anti-deadzone for anyone interested: https://github.com/csutorasa/XOutput/files/8487111/XOutput-with-AntiDeadzone.zip
