Tuning data files mostly use spaces for indentation, with occasional
stray tabs. Use spaces consistently. This allows parsing the tuning
files with libyaml, preparing to replace the dependency on boost.

Increase the maximum allowable gain from 6.0 to 8.0 in the normal and short
exposure profiles for all camera sensors. Increase this limit to 12.0 for the
long exposure profiles for sensors where this has been defined.
The 6.0x value was somewhat arbitrarily chosen, and does limit the total
exposure in dark conditions.

"NOIR" modules are ones that have had the IR filters removed but are
otherwise identical. The same tuning can be used as for the regular
version except that the colour calibration supplied to the AWB
algorithm no longer works. Instead we need to switch the algorithm to
its basic "grey world" method.
Users with "NOIR" modules can switch to the matching "xxx_noir.json"
tuning file by using the LIBCAMERA_RPI_TUNING_FILE environment
variable.
