bug: cellid (node number, disv) supplied as int to ModflowGwfmaw written as float

[RyanConway91]

Describe the bug
I am providing the node number in the connection data block as an int to ModflowGwfmaw. When I query the data before writing the model input files, this value is shown as an int:

however, when I write the model files, this value is written in exponential format causing an error in mf6.

To Reproduce
Steps to reproduce the behavior:
Put MAW in disv model with a high number of ncpl (my model has ~300k ncpl)
Expected behavior
ints should stay ints

Desktop (please complete the following information):

• OS: windows
• Version '3.3.7'

Your connectiondata has "layer" and "node" columns. All of the cellid information should be stored in the same "cellid" column (layer, node for disv) as a tuple. See the description for maw connectiondata here:

https://github.com/modflowpy/flopy/blob/develop/flopy/mf6/modflow/mfgwfmaw.py

cellid ((integer, ...)) is the cell identifier, and depends on the type of grid that is used for the simulation. For a structured grid that uses the DIS input file, CELLID is the layer, row, and column. For a grid that uses the DISV input file, CELLID is the layer and CELL2D number...

Thank you, providing cellid as a list of tuples fixed the issue. Is this example out of date then?

https://modflow6-examples.readthedocs.io/en/latest/_notebooks/ex-gwf-maw-p01.html#

in this example, cellid is not provided as an iterable, but as ints.

The example is still up to date, the cell IDs may be provided as ints or iterables of ints. However the usage must be consistent, whichever you go with
