USGS internal data pulls are possible

[thodson-usgs]

I need to document this, but internal NWIS data pulls can be made by setting the access kwarg.
For example

nwis.get_record(sites='05404147',service='iv', start='2021-01-01', access='3')'

Notes from the R package source:

setAccess = function(access="public"){
  
  access = match.arg(access, c('public','internal','cooperator','USGS'))
  
  if(access=="internal"){
    pkg.env$access = '3'
    message('setting access to internal')
  } else if(access=="cooperator"){
    pkg.env$access = '1'
    message('setting access to cooperator')
  } else if(access=="USGS"){
    pkg.env$access = '2'
    message('setting access to all USGS Water Science Centers')    
  } else {
    pkg.env$access = NULL
    message('setting access to public')
  }
