camtrapR modernisation

[jniedballa]

Just a few ideas for potential future improvements:

Functions:

• [x] community occupancy models
• [x] detectionMaps: use sf instead of sp for shapefile export
• [x] multi-hierarchy metadata tag support (at least for species)
• [x] date and date/time arguments use lubridate syntax by default, maybe also internally (changed default arguments)
• [x] function for filtering for temporal independence in existing record tables
• [x] exiftoolPath -> addtopath()
• [ ] detectionMaps: plot with ggplot. Optional basemaps (e.g. leaflet)?
• [ ] activity... -> ggplot. Maybe one umbrella function with e.g. type = "radial", "density", "histogram" (also removes plotrix dependeny )
• [ ] parallel processing, e.g. recordTable / imageRename
• [ ] lifecycle to soft-deprecate old functions
• [ ] allow multi-season models with camera IDs?
• [ ] timeShiftImages at any stage of workflow
• [ ] detectionHistory(): support occasions shorter than 1 day

Documentation

• [x] roxygenize, add @importFrom ...
• [ ] vignette section on importing existing data
• [ ] update & extend vignettes

Other

• [x] replace raster / sp with terra / sf
• [x] replace snow with parallel
• [x] Shiny surface, at least for some important functions?
• [ ] read / write / convert camtrapdp data (maybe even change data structure used in camtrapR if camtrapdp gains traction)
• [ ] fast metadata writing possible? (e.g. write station tag in HierarchicalMetadata, sth like writeDateTimeOriginal)
