add vmm grid support

[barisoztas]

Hi @stijnvanhoey , after our discussion on how to support for the raster data products, I could work on the remaining issues and now here we add support for:

• KiWIS vmm grid api
• requesting raster data as BytesIO
• parsing the response as xarray.Dataset

Changes

1. For pywaterinfo to support raster data, an extension for the Waterinfo.request_kiwis() method is made. Now, it is possible to pass return_bytesio: bool argument to optionally return raw binary data (via BytesIO), enabling support for file downloads and non-JSON responses from the grid API.
2. To parse the raster response of request type getRasterTimeseriesValues as xarray Dataset, parse_waterinfo_hdf5() is added. (which I believe the module parser.py should also hold the specific json parsing logic for getTimeseriesValues, getTimeseriesValueLayer, getGroupList, getTimeseriesList request types)
3. To support the new kiwis request type getRasterTimeseriesValues, Waterinfo.get_raster_timeseries_values() method is added

I really enjoyed implementing and exploring the data on a map. I hope you also enjoy reviewing and giving it a try 😃

closes #66 . However there are still room for improvements for VMM-Grid api (more request types are available such as GetRasterToPointValues, GetRasterFile)

Thanks for fitting it in the current implementation withou big refactorings.

I do have some comment, but should be easy to update.

[stijnvanhoey]

Good idea, thanks. Also relevant for @TimFranken

Thanks for the review @stijnvanhoey . I adjusted your comments, and provided a little bit more detail about the attributes of the hdf5-file. The PR is ready for review again.

[stijnvanhoey]

Thanks a lot, with these adjustments I do think we are good to go

[stijnvanhoey]

Thanks, good to have this feedback to the user

Still a depdency issue

Still a depdency issue

now we hit to pytz issue also here in this PR -> https://github.com/fluves/pywaterinfo/actions/runs/24124066789/job/70384387893?pr=76

I propose we first merge #77 as we will remove pytz dependency which will hopefully solve also the issues in this PR

I have also updated python versions of the CI pipelines for pypi deployment and documentation building (3.9 -> 3.11)

Thanks for the update and adjustments, ready to merge!
