Expose nc_rc_set

[magnusuMET]

• python-netcdf 1.6.5-2
• netcdf 4.9.2
• Arch Linux, python 3.12.3
• Can't call nc_rc_set to set custom configuration

In newer versions of netCDF one is required to explicitly set a path to e.g. .netrc, see Unidata/netcdf-c#1966. I can't seem to find a way to call this function from python as this function is not exposed.

PR #1348 exposes nc_rc_set (via rc_set) and nc_rc_get (via rc_get).

For some reason, nc_rc_get triggers a segfault (crashing the python interpreter) if you ask for a non-existent key. @DennisHeimbigner is this to be expected?

NVM the above comment - I needed to check for a NULL pointer returned from nc_rc_get

@magnusuMET would you be able to test PR #1348 to see if it resolves your issue?

[magnusuMET]

As far as I can tell this sets the key appropriately. I am seeing an issue where the key is not used by netcdf-c, but I think that is an unrelated issue
