bugfix_vectorized_vaccineautodetect

[ppreshant]

Lots of changes here. Summary of important changes

1. process_all_pcr: Vectorized general function to process ddpcr, std and qpcr runs; incl baylor_wells
2. sample registry: Automatic merging of volumes for biological replicates if weight entry is absent
3. Automatically detecting vaccine wells and appending data to respective sheets (raw vaccine data, and vaccine_summary)
4. Calculations_multiple_runs/Sample_names: Retaining the min of consecutive dates as the Sample_name for proper facets

Minor

• make_html_plots: Corrected empty tibble checking: plyr::empty()
• bugfix: Baylor - vol_B: proper regex join by Sample_name
• template_volume: renamed to template_volume_qpcr/ddpcr to prevent confusion
• Automatic data addition in WWTP data for HHD
• WWTP data: format change: Copies_per_ul (removed RNA), WWTP to Facility_ID
• Weekly_comparison: correcting for missing column names
• processing_functions.R/formatting: Breaking comments in different lines, for shorter width
• Error fix: Ignoring Std and NTC samples if assigned as baylor (still output but not sent into volumes pipeline)
