Raster filter based on prefix/suffix

[tlarcher]

Is your feature request related to a problem? Please describe.
Currently, when using GLC23 raster datasets it is possible to filter loaded rasters based on their entire name, or their channel in the case of satellite images. But it is not possible to finely select files with a regex-like filter on the files' name.

Describe the solution you'd like
Either a similar solution to RasterTorchGeoDataset where both a glob and a regex expression are provided; or additional arguments prefix and suffix which would take a strings as input.

Describe alternatives you've considered
