Feature/issue 186 Optional NRT label in the filenames

[ank1m]

GitHub Issue: #186

Description

Filename regex pattern used for TEMPO collections fails because for NRT collections extra _NRT_ label is included in the filename.
For example, for standard collections, say TEMPO_HCHO_L2_V04_20250101T000000Z_S001G01.nc

But in case of NRT collections, additional suffix _NRT_ is present: TEMPO_HCHO_L2_NRT_V04_20250101T000000Z_S001G01.nc
So extra regex term needs to be included to capture optional _NRT_ suffix, similarly to proxy term:
