ipa: raspberrypi: Introduce version 2.0 format for the camera tuning file
The existing tuning file format (version 1.0) requires the controller algorithms
to run in the same order as listed in the JSON structure. The JSON specification
does not mandate any such ordering, but the Boost JSON parser would maintain
this order.
In order to remove this reliance on the parser to provide ordering, introduce a
new version 2.0 format for the camera tuning file. In this version, the
algorithms are specified in a top level list node ("algorithms"), which does
require strict ordering of the elements.
A "version" node is added to distinguish between the version 1.0 and 2.0
formats. The absence of the "version" node implies version 1.0.
A "target" node is also added to specify the target platform for this
configuration.
Update the controller to support either version of the tuning file by looking
at the version node. CreateAlgorithm member function to now load and configure
each algorithm. Additionally, make CreateAlgorithm a private member, it does not
get called externally.
If a version 1.0 format tuning file is used, throw a warning message indicating
it will be soon deprecated.
