String / Array working length of 4096 is too long (as of 6/9/18)

[Deequeue]

Re-ran the file screen script on 3/9/18 and 6/9/18 - worked on 3/9, but as of 6/9 the updates pulled from the fsrm.experiant.ca api break the import of file groups into FSRM, subsequently the creation of the File screen templates and filescreens fail.

Group3 fails to create due to the array being 4096 chars "long" (including 1 char per ',' -1 for the final entry) however testing during the day I have also seen the issue with Group6.

Reducing the string limit to 4095 in New-CBArraySplit function resolves the issue.
