wasserportal: read_wasserportal not working in case of "single" variable

[mrustl]

remotes::install_github("kwb-r/kwb.read@dev")
id <- "5865900"
kwb.read::get_wasserportal_variables(id) 
>Wasserstand 
>       "w" 
kwb.read::read_wasserportal(id)

The problem is that the default date is "2019-01-01" and that currently only single values can be requested. The single values are not available for such a long period back in time.

This should work:

kwb.read::read_wasserportal(id, from_date = "2020-01-01")

        LocalDateTime UTCOffset Wasserstand

I am working on an argument type that allows to get also the daily and monthly values. These should be availble further back in time.
