Add waterdata demo

[ehinman]

Built off the PR that adds reference table functions.

Adds a demo of the waterdata functions to drpy. Addresses: #200

Also adds a few query parameters to the get_time_series_metadata() function.

This is great! I appreciate the consistent throughline example. I've just a few comments that you might consider, but I'm only requesting changes on the errors I ran into (the double monitoring_location_id error + the GeoPandas-dependent code).

Might be good to link to the specific OGC API homepage somewhere -- maybe here? https://api.waterdata.usgs.gov/ogcapi

Will add to resources section.

End the vignette with a list of links/resources to learn more

@jzemmels I think this is ready for a second look. I have fixed the duplicated ID column issue in the waterdata/utils.py (for some reason I can't link to that page right now, GitHub being weird). I added resources, more links, and reduced plotting duplication, inspired by your inquiry about matplotlib! I have articulated that matplotlib and geopandas are required to run the entire notebook, but the waterdata functions do not require them.

The one little hitch I've run into is that there was some discussion in the get_reference_table() MR (merged) about whether the "you don't have geopandas in your environment" logging message should be a warning or an info-level message. I had switched it from warning (prints in the console when running the function) to info (only prints if you request it), but switched it back following Tim's suggestion. Unfortunately, the way I've coded the reference table function, this means that it will warn you you don't have geopandas installed, even if you do. I need to get more creative with how this all works. I think I will address in a separate PR to limit confusion.

Yep, these changes all look great. Other than populating the additional resources section and one minor comment, I think this is good to go. Approved.

@jzemmels Are there any that you would add?

Thanks so much for the help!
