[R] rerddap v1.2.0

I am pleased to announce that rerddap v1.2.0 is now on CRAN. The major changes are that 'tabledap()' now has the option to download the data as parquet files if the ERDDAP server is at least version 2.25, and the data frame created by 'tabledap()' now has the units as attributes. There are
