camtrapR modernisation

[jniedballa]

Just a few ideas for potential future improvements:

Functions:

• community occupancy models
• detectionMaps: use sf instead of sp for shapefile export
• multi-hierarchy metadata tag support (at least for species)
• date and date/time arguments use lubridate syntax by default, maybe also internally (changed default arguments)
• function for filtering for temporal independence in existing record tables
• 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

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

Other

• replace raster / sp with terra / sf
• replace snow with parallel
• 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)
