GstBase.Adapter.map() and GstBase.Adapter.take() have missing parameter

GstBase.Adapter.map() and GstBase.Adapter.take() do not currently accept the size and nbytes arguments in the python bindings even though the documentation mention them when describing the functions:

• http://lazka.github.io/pgi-docs/GstBase-1.0/classes/Adapter.html#GstBase.Adapter.map
• http://lazka.github.io/pgi-docs/GstBase-1.0/classes/Adapter.html#GstBase.Adapter.take

These parameters are there in the C API:

• https://developer.gnome.org/gstreamer-libs/stable/GstAdapter.html#gst-adapter-map
• https://developer.gnome.org/gstreamer-libs/stable/GstAdapter.html#gst-adapter-take

These shortcomings can be worked around by using GstBase.Adapter.take_buffer*() functions which seem to work fine and can substitute the broken ones.

This file shows the problem for GstBase.Adapter.take(): test_GstAdapter_take.py
