Update San Joaquin spawning and rearing habitat to expand to include upper san Joaquin reaches.

[ErinCain]

For rearing habiat update:

• [x] Create a flow to suitable acres curve from each reach based on "tidy_rearing_data_sjrrp_fish_habitat_study_results.csv"
• [x] Combine reaches using weighted mean based on reach length - reach length can be found in SJRRP Fish Habitat Study - Final 2012.docx. See feather RMD for an example of what this looks like https://github.com/CVPIA-OSC/DSMhabitat/blob/main/data-raw/watershed/feather/feather_river.rmd
• [x] save upper_san_joaquin_river instream data object
• [x] Update cache habitat script (or maybe just add baseline habitat script) to calculate total san joaquin hab as current hab + additional upper hab (use upper hab instream data object to calculate monthly habs) - save as an update to r2r_baseline hab objects

For spawning habitat

• [x] use this data "san_joaquin_spawning.csv" - from this report Draft_metadata_2Dmodelprocessed_bothreaches_ADA.pdf
• [x] Same gist but currently no spawn hab in san joaquin so just add new spawning hab into r2r_baseline spawn data objects

After updating both go into fallRunDSM, reinstall DSMhabitat, and

• [ ] save and rerun params
