Adapt LayerData upload scripts

[micah-prime]

Adapt the scripts for uploading LayerData to the new table organization using the class in snowex_db.upload.layers in this PR #39

Scripts include:

• add_alaska_pits_2023.py
• add_iop_pits.py
• add_smp.py
• add_ssa.py
• add_time_series_pits_2020.py
• add_time_series_pits_2021.py

Each script will need to upload the site properties csv before the rest of the data to ensure the Site table is populated with the environment info first

@micahjohnson150 FYI here is the start of this issue

@micah-prime , @micahjohnson150 are all the raw data files accessible on NSIDC? If not, is there a way I can access preliminary data folders for testing and development?

The data files are accessible on NSIDC. The easiest way is running the download scripts like https://github.com/SnowEx/snowex_db/blob/main/scripts/download/download_nsidc.sh
but change what is in https://github.com/SnowEx/snowex_db/blob/main/scripts/download/nsidc_sources.txt first or you'll get a lot of datasets
Also, this requires your netrc to be populated I believe
