In birdscanR: Migration Traffic Rate Calculation Package for 'Birdscan MR1' Radars

birdscanR 0.3.0

Added functionality: The function 'computeDensity()' was added to calculate the density (expressed as #objects / km3). Note that this function only works for Birdscan MR1 database versions >= 1.7.0.4 as the variable feature37.speed is required for the density calculation (#40{.uri}).
Added functionality: The function 'getBatClassification()' was added to get the data from the MR1 SQL tables 'bat_classification' and 'bat_class_probability'. The function 'extractDbData()' was updated to also extract the bat classification results using the prior function (#36{.uri}).
Added functionality: The function 'reclassToBats()' was added to change the class of the echoes to 'bat' for those having a classification probability higher than a specified threshold (#36{.uri}).
Added functionality: The 'feature37.speed' from the new Birdscan software v 1.7 is now also being extracted when calling the function 'getCollectionTable()' (#39{.uri}).
Bug fix: Conditional 'if (exists("mtrDayNight", envir = environment()))' caused bug in 'computeMTR()' function when variable was already defined in a user script (i.e., outside of the package). This has been fixed (#38{.uri}).

Added functionality: Add sample classification into crepuscularMorning, day, crepuscularNight, and night when extracting data.
Added functionality: Enable mtr calculation for day, crepuscule, and night instead of merely day/night only (both options available now).\
Bug fixes: Small bug fixes in the two plotting functions.
Bug fix: sunrisesunset information was being deleted for locations at higher latitudes because of the lack of the sunrising or setting. This has been fixed.
Dependency fix: maptools package is retiring; Moved to suntools package which has the same functionality for twilight calculations (#34).
