Currently the wrapper tries to figure out which version of
the esp-idf-size should be started. The legacy version is
used if explicitly requested by the -l/--legacy option or
if json format is specified. This works fine, but if help
is requested, it is printed for the wrapper as shown bellow
$ idf_size.py -h
usage: idf_size.py [-h] [--format FORMAT] [-l]
options:
-h, --help show this help message and exit
--format FORMAT
-l, --legacy
This is not convenient and the full help from the underlying
version should be displayed.
Fix this by only peeking into the args to figure out if legacy or
refactored version should be started and always spawn the underlying
esp_idf_size python module. This is done by using exit_on_error=False and
add_help=False for the ArgumentParser. When help for refactored version
is requested a note as following is printed to notify users that the
legacy version can still be used.
$ idf_size.py -h
Note: legacy esp_idf_size version can be invoked by specifying the -l/--legacy
option or by setting the ESP_IDF_SIZE_LEGACY environment variable.
