Change species table of parameters/traits

Changes longevity values in the species table according to Burton & Cumming (1995). Only the species and values present in Boreal Shield West (BSW), Boreal Plains (BP) and Montane Cordillera (MC) speciesTable$Area are being changed. All others follow Dominic Cyr and Yan Boulanger's trait values (https://raw.githubusercontent.com/dcyr/LANDIS-II_IA_generalUseFiles/master/speciesTraits.csv). Note that BSW and BP areas correspond more closely to the region considered in Table 2 of Burton & Cumming (1995), while MC will correspond to both tables.

sppEquiv	table with species name equivalencies between the kNN and final naming formats. See data("sppEquivalencies_CA", "LandR"). Only necessary if mixedType == 2. If not provided and mixedType == 2, will attempt to use data("sppEquivalencies_CA", "LandR").
sppEquivCol	the column name to use from sppEquiv. Only necessary if mixedType == 2. If not provided and mixedType == 2, will attempt to use "Boreal".

Value
