Add z_bias_map schema

[dachengx]

It is a time interval piece-wise correction.

Thanks @dachengx !

Just one thing missing, the fields of the schema :)
Inheriting from TimeIntervalCorrection will add the version: str and time: TimeInterval fields but there is no fields defined to hold the map.
I see now that the maps will be stored in private_nt_aux_files so i guess this schema will only store the file name for each time period? In that case either add a value: str field or inherit from the BaseMap schema which has a value field of type string.
from .base_references import BaseMap, but BaseMap also has the algorithm field which may not be relevant.

Another more advanced option would be to add a field called e.g. filename: str and add a property named value which loads the file when accessed. I didn't do this for the BaseMap class because i was afraid it may confuse people.

Usually we name the collection alias plural, so here it would be z_bias_maps just so it makes more sense when people try to access the data from xedocs.

[dachengx]

If add a property value, and we know that the map is in .json.gz, then shall I open the file inside value? I think this is done by a straxen fucntion.

[jmosbacher]

For simplicity, maybe just make it similar to what we did for all the other maps.

Have you had a look at the xedocs.schemas.corrections.base_references.BaseResourceReference class?
This class checks that the file exists in MongoDB before inserting it into the DB.
Would this kind of check also be useful for this map?

Sorry, I misunderstood your point. I think BaseResourceReference is certainly better.
