Indi-pylibcamera

- support for monochrome cameras
- support for new raw and RGB frame formats (including monochrome)
- disable astropy to download the latest IERS-A table from internet to avoid errors during observation session
- better stability of exposure loop

- fixed changed data alignment in Pi 5 raw images

- added INI switch "force_Restart" and implemented camera restart (solves crashes for IMX290 and IMX519)
- forwarding log messages to client

- update FITS header formatting and timestamps
- use lxml for construction of indi_pylibcamera.xml
- renamed SwitchVector FRAME_TYPE(FRAMETYPE_RAW, FRAMETYPE_PROC) to CCD_CAPTURE_FORMAT(INDI_RAW, INDI_RGB)
to better support AstroDMX
- removed "setSitchVector CCD_ABORT_EXPOSURE" after each exposure start (that did not allow CCDciel to run
exposures in loop)
- reworked handling of CCD_ABORT_EXPOSURE
- fixed Fast Exposure

- fixed Bayer pattern order for HQ camera (pycamera2 or libcamera have change they way they report Bayer pattern order),
BAYERPAT in FITS does not depend on "Rotation" property anymore (force_Rotation has no effect anymore),
but Bayer pattern can now be forced with force_BayerOrder
- sorting raw modes by size and bit depth to make the mode with most pixel and most bits/pixel the default
- saving and loading configurations
- bug fix: after aborting an exposure the camera stayed busy and EKOS field solver could not start a new exposure

- fixed division by 0 when focal length equals 0
- improved driver exit when indiserver is closed (to avoid driver continue to run)
- more transparent implementation of snooping; snooped values are now also available as driver parameter
(in tab "Snooping")
- removed empty line and XML declaration from driver XML
- added driver vectors for camera controls (allows to enable automatic exposure control and AWB)
- added uninstall instructions in README.md
- minor improvements
