Removing `here::here()` from rAccess constructor

[nikolas-burkoff]

When creating the rAccess constructor with a config file the path is wrapped in a call to here::here() see code.

This (silently) changes the path to the config file.

I'd normally expect the creator of the class to make the here call, i.e. rAccess$new(config = here::here("my_config.yaml") )
