The version string of libcamera is presently appended with a date/time
argument in the case of a dirty tree to show further detail of when it
was built. This string is generated with the iso-8601 parameter to
'date' and produces a date string in the form:
"2024-06-17T22:15:30+01:00"
Strict posix shells or implementations of 'date' which may be optimised
for size such as the one provided by busybox or Alpine Linux may not
support the '--iso-8601' flag.
To support builds on those platforms, use a direct POSIX-compliant
date-format string instead matching as closely as possible to the
iso-8601 definition.
An exact match is not possible with those restrictions so 'date
%Y-%m-%dT%H:%M:%S%Z' is used which produces 2024-06-17T22:15:30BST.
The use of the human readable timezone identifier provides a friendlier
output for the string than a timezone offset at the expense of being
less sortable in the exceptionally low risk and unlikely event of two
custom builds being compared at the same time of different timezones.

With the addition of gamma out correction the relative luminance target
was set too low. As brightness is a bit subjective it is difficult to
come up with the "correct" value. With 0.5 the patch 22 on the macbeth
chart (neutral grey, 18% reflectance) ended up a bit below 50% grey,
which seems reasonable.

In cases where the calibration image contains super dark areas, or when
an invalid blacklevel was supplied, the grid might get close to zero or
negative. This would have bad effects on the 1/grid later. So clamp the
values to a small positive number.

The current LSC algorithm for the rkisp1 just forwards the LSC tables to
the hardware, so absolute factors are needed and not ratios compared to
green. Therefore every channel needs to be calculated independently.

Add awb, blc, cproc, filter, and gamma to the tuning file. These don't
need any configuration.
At the moment there are no inter-module dependencies in the tuning
process. We can therefore safely sort them alphabetically. As soon as
the first dependency gets introduced (most likely lsc -> ccm) we will
see how to solve that.
The output order controls the order of processing in the IPA. It is now
also in alphabetical order which happens to be no change for the modules
that existed previously. For the others, there is no need for a specific
order.

Port commit 66479605baca ("utils: raspberrypi: ctt: Improve the Macbeth

Previously the code would brighten up images in case the Macbeth Chart
is slightly dark, and also zoom in on sections of it to look for
charts occupying less of the field of view. But it would not do both
together.
This change makes the search for smaller charts also repeat that
search for the brightened up images that it made earlier, thereby
increasing the chances of success for non-optimal tuning images.
