Add support for OGC API Processes

[huard]

Description

OWSLib now has support for OGC API Processes. Not clear if the birdy WPSClient can be adapted, or if we'll need to create a new OGCAPIProcessesClient.

Rather than reimplementing your own: https://github.com/crim-ca/weaver/blob/d4ffd34e8cc33a3b08ab39779d72406023565d81/weaver/cli.py#L382

Docs: https://pavics-weaver.readthedocs.io/en/latest/cli.html#python-client-commands

Should be as "latest" as possible in terms of support of OGC API - Processes, since this is way I use to test anything proposed to the SWG + all the bells and whistles of CWL+WPS support.

The birdy client creates a mock python module out of the process definitions. I didn't see that in weaver, correct ? But I suspect it'd be easier to build this on top of weaver than OWSLib ?

You can use this function for OWSLib to OGC API Processes:
(ignore the first CWL output, the second JSON output is the OAP process description)
