DTSg v1.0.0

• Added funbyApproach argument to new(), aggregate(), colapply() and subset() methods: allows for specifying the flavour of the applied temporal aggregation level functions (either "base" utilising as.POSIXct() or "fasttime" utilising fasttime::fastPOSIXct() or "RcppCCTZ" utilising RcppCCTZ::parseDatetime() as the main function for transforming timestamps). Custom approaches for user defined TALFs are also possible. Please note that the byFasttime* versions of the TALFs are now deprecated. Use this argument from now on instead.
• Added funbyApproach also to the list of helper data (funbyHelpers argument) passed on to TALFs.
• Added funbyApproach field reflecting the individual funbyApproach of a DTSg object (can also be actively set in order to change the utilised approach).
• Added undocumented names() method exclusive only to the R6 interface acting as an alias for the cols() method.
• Added mode and typeof arguments to cols() method: allows for getting column names with a certain mode() and/or typeof(). This can be especially handy when making use of the units package.
• Added DTSgFast, DTSgFunbyApproach and DTSgNA.status options providing default values for the fast, funbyApproach and na.status arguments of the new() method.
• Added DTSgDeprecatedWarnings option: allows for disabling warnings from deprecated features.
• Greatly sped up by______() and byFasttime______() TALFs.
• It is no longer possible to use the deprecated value "all" with the class argument of the cols() method in order to get all column names. Use the default value NULL instead for this. "all" is treated as a filter for classes of type all from now on.
• Added an example to the setCols() method showing how to set measurement units with the help of the units package.
• Added an example to the documentation of the colapply() method showing how to calculate running correlations with the help of the runner package.
• Bumped minimum tested R version from 3.5.2 to 4.0.2 using the corresponding MRAN repository snapshot.
• Slightly improved documentation.
• Minor internal code improvements.
