Describe the bug
The default value for coordinate_check_method in ModflowPrtprp of 'eager' gives the following error in latest MODFLOW-(verion 6.6.3):

ERROR REPORT:

  1. Input tag "COORDINATE_CHECK_METHOD" read from file
     "from_scratch_prt.prp" is still under development. Install the nightly
     build or compile from source with IDEVELOPMODE = 1.

Therefore I think the default value in FloPy should be None.

Expected behavior
No error in latest MODFLOW

Desktop (please complete the following information):

• OS: Windows
• Version FloPy: 3.10.0, MODFLOW: 6.6.3
