Reduce the number of dependencies

[Moohan]

R-CMD-CHECK give a build note commenting on the large number of dependencies we have. It would be sensible to review this and reduce them where possible. We should take a systematic approach and where we are depending on a package but only using it in limited places we should try to re-write the code to not require it.

An obvious example would be to replace glue::glue(...) with stringr::str_glue(...) Since we use {stringr} for many other functions.

Uses hms package

• process_extract_cmh.R - keytime2
• process_extract_gp_ooh - keytime1 and keytime2

Uses R markdown package

• process_costs_rmd.R - not sure if we use this

Uses scales package

• costs_care_home.Rmd I don't think we use any of these scripts?
• costs_district_nursing.Rmd

• hc_methodology

Uses stringdist package

• fill_ch_names.R used for jaccard and cosine matching

Uses tarchetypes package

• _targets.R

Uses zoo package

• process_extract_consultations.R - zoo::na.locf I think this is the same as fill but possibly specialised for dates?
