Add a new parameter to the pipeline handler config file named
"unicam_timeout_value_ms" to allow users to override the automatically
computed Unicam timeout value.
This value is given in milliseconds, and setting a value of 0 (the
default value) disables the override.
An example use of this parameter would be if an application configured a
RAW stream, and provides buffers for the stream on every request. If the
application holds off on sending requests for a particular reason (e.g.
a timelapse use case), then we will possibly hit the watchdog timeout as
it is only a small multiple of the frame length. This override allows an
application to select a larger value with the knowledge that it may
space requests longer than the calculated timeout value.

Add the ability to read the platform configuration parameters from a
config file provided by the user through the LIBCAMERA_RPI_CONFIG_FILE
environment variable. Use the PipelineHandler::configurationFile()
helper to determine the full path of the file.
Provide an example configuration file named example.yaml. Currently two
parameters are available through the json file:
"min_unicam_buffers" The minimum number of internal Unicam buffers to
allocate.
"min_total_unicam_buffers" The minimum number of internal + external
Unicam buffers that must be allocated.
