Overriding import mode per BOI in M3 Import program

Previously, it was possible to override the import mode used by the M3 import program per BOI. This was enabled in a BOI using the XML tag <INCREMENTAL_IMPORT>. This feature is now deprecated.

Currently there are no BOIs in the standard M3 integration that use the <INCREMENTAL_IMPORT> tag. The only M3 BOI with the tag in its XML definition has been MMS200MI_LstItmByChgDate_ST_M3_IN_MMS200MI_LstItmByChgDate; this BOI has been updated in SCP v21.3 to remove the <INCREMENTAL_IMPORT> tag.

The EPOCH time support together with the additional parameters to the M3 Import program, which have been introduced in SCP v21.3, can be used to import planning data from M3 in incremental mode.
