Feature: joystick weights

[daliusd]

Joystick weights.

Description

I have played around with different algorithms how joystick should work and found out that default x^2 weighting is not necessary optimal. Therefore I have added possibility for user to override weighting for lever positions.

Types of Changes

• Core
• Bugfix
• New feature
• Enhancement/optimization
• Keyboard (addition or update)
• Keymap/layout/userspace (addition or update)
• Documentation

Checklist

• I have read the PR Checklist document and have made the appropriate changes.
• My change requires a change to the documentation.
• I have updated the documentation accordingly.
• I have read the CONTRIBUTING document.

Here I have written blog post how I came up with this: https://blog.ffff.lt/posts/joystick-algorithms/

Don't have any joysticks so can't test, but I don't see anything of concern here.

Hey, I have two more changes related with analog joystick, but they are kind of related to this one: automatically resolving min/max axis values and one change that makes joystick behave slightly differently. Should I wait until this PR gets merged or there are other options? cc: @drashna

That entirely depends on you. Adding more to it would mean that it's definitely gonna be longer to get approved. But it's merge month, so ... it may not make it anyways. So it's up to you.

That said, if this is all for joystick code, I'd say roll it into this PR.

Hey, I have added two more features to joystick code. Please review again.
