Prescription extraction fixes and improvements

[lucy-schick]

Turns out that the first ncfdc_1998_prescriptions_clean.csv was pretty draft and there were lots of things to fix.

https://github.com/NewGraphEnvironment/restoration_wedzin_kwa_2024/blob/main/scripts/extract-tables-ncfdc-1998.R was the script used to make that csv, I'm pretty sure I wrote the prescription part and I remember it being pretty rough. Anyhow, cleaned it up big time.

I made a new script called extract-prescriptions-ncfdc-1998.R and copied over the old code from extract-tables-ncfdc-1998.R. Now extract-prescriptions-ncfdc-1998.R contains all the code to extract the prescriptions. I removed the old code from extract-tables-ncfdc-1998.R which now only contains code to extract tables (makes sense to me with the name).

A couple changes to the new extract-prescriptions-ncfdc-1998.R :

• read in pdf, cleaned it up, then separated it into a list where each element is 1 prescriptions. This means we didn't have to check if sub-basin was not present as per comment here restoration sites historic - Prescriptions - Regional District of Nadina - Community Futures #48 (comment)
• added utms as per slack messages
• fixed up lots of the regexs so now all info is matched properly
• added some more columns to accommodate survey, design, cost info.

I did run through https://github.com/NewGraphEnvironment/restoration_wedzin_kwa_2024/blob/main/scripts/extract-tables-ncfdc-prescription-elements.R which was helpful but https://github.com/NewGraphEnvironment/restoration_wedzin_kwa_2024/blob/main/scripts/extract-tables-ncfdc-1998.R had more of what we needed

Can close #48 once this is merged.

Need to go reopen #45 once this is merged because I accidentally put the wrong issue number in the commit, see #45 (comment)

Awesome. Thanks!

Will be interesting to see what is different between what we have extracted here and the files dug up from SKT that are on the google drive link. Will turn this into a spatial file ASAP and add to the project in the meantime. Wonderful!!!!
