Modify full pipeline to projected crs

Projection issue

[Disclaimer: The following comment comes from someone who is not a geographer. Someone with more insight into the topic is encouraged to add/correct any inaccuracies or oversights]... but, we should maybe touch on projections a little bit. Everything now is now being projected to the specified_crs of EPSG: 4326, which is essentially unprojected and, especially if we turn off spherical geometry (see comment on line 15 of 2_process/src/scope_lake_tributaries.R, potentially going to lead to some inaccuracy. What makes this tricky is that leaflet requires things to be in EPSG 4326, from what I can tell. So, if we are going to send them shapefiles or use any of our products for analysis or measurement at all, I suggest that we make sure that we project the data into a different coordinate system, like EPSG 5070 and we can just project it back to 4326 just for plotting in leaflet.

To do:

• Initiate new PR and modify all spatial files in pipeline to new projected crs.

Not sure if this is still immediately relevant. 4326 seems to work for our purposes.
items to come back to after addressing feedback.

labeling as a learn more and 'enhacement` issue because do not think this change will impact our output.
