v0.11.0

Added

• speed-mode lazy|slow|normal|fast|very-fast|auto sets the finer tracking speed (0x0944) and
  speed headroom the third vertical tracking type (0x0cc4 = 1). status.framing reads the
  speed mode and the options below back. Capabilities speed_mode, speed_headroom (#64).
• framing auto-zoom|size|zoom-speed|offset|part sets the options the AI modes are made of
  (0x0a44, 0x0ac4, 0x0b44, 0x0bc4 / 0x0c44, 0x1584); status.framing reads them back.
  Capability framing (#84).
• gimbal rate --pan R --tilt R turns the gimbal at a speed until gimbal stop (0x6484, the
  joystick of OBSBOT Center; it does not limit absolute moves). The camera reverses its yaw when
  mirror xor invert is on, which obsbot4linux undoes. No capability gimbal_rate: the camera
  has no timeout, so a client that dies leaves it turning. Capability gimbal_stop (#78, #80).
• gimbal --pan P --tilt T --speed S moves at S degrees per second (0x6544), zoom F --speed S
  zooms smoothly (0x6884) and zoom stop / gimbal stop stop (0x68c4, 0x6704). Capabilities
  gimbal_speed, zoom_speed (#80).
• gimbal center X Y (0x0544), which moved the gimbal only toward the left and downwards in
  tests, see the README. Hidden from --help, no capability (#83).

Changed

• status.tracking_speed can now be headroom: the camera value 1 of 0x0cc4 used to show as
  standard.
