Thanks, Mark - this is great! I hope Angle users find it helpful.

Important note - the value for 'Angle Center Sensitivity` is effectively in degrees; it is the angle you'd get, in Angle Mode, at max stick position, if the centre sensitivity was held the whole way to full stick travel.

This value allows Angle Mode pilots to get a value that precisely indicates their centre stick sensitivity for Actual or Betaflight Rates; the values are directly comparable between both Rates models.

Note also that centre stick sensitivity in Angle Mode will change if the user modifies their angle_limit value. The centre sticks sensitivity value shown here correctly adapts to angle_limit changes.

Some images showing the numbers you might see, all with the default angle_limit of 60...

Default Actual Rates, showing weak centre sensitivity of only 6.3:

Betaflight Rates, showing default centre sensitivity in Angle Mode of 18 - three times 'twitchier' than the default for Actual Rates...

Actual Rates, modified with values that closely resemble default Betaflight rates, with approximately the same centre sensitivity:

Works really well!
