[C++] Deprecate Feather reader and writer

[pitrou]

Describe the enhancement requested

This was discussed on the ML and there was a general agreement that deprecating both the Feather reader and writer is reasonable.

The actual API removal can be differentiated: the writer may be removed in version N +1 (24.0.0?) while we could wait a bit longer to remove the reader (28.0.0?).

Component(s)

C++

@kou @thisisnic @jonkeane Could you perhaps open issues for C/GLib/Ruby and R, respectively?

[kou]

Yes:

• For R: [R] Deprecate Feather reader and writer #49237
• For GLib/Ruby: [GLib] Deprecate Feather reader and writer #49252

Do we also need a ticket for MATLAB here too?

@sgilmore10 @kevingurney Could you work on this for MATLAB?

@sgilmore10 @kevingurney Could you work on this for MATLAB?

@kou - Yes, I'll create an issue for deprecating the MATLAB API, and either @kevingurney or I will work on it.

FYI - #49705 has been opened for introducing deprecation warnings for the MATLAB interface.
