Event ID should not exceed MAX_INT when converting footprint file from csv to binary

[hchagani-oasislmf]

Issue Description

Model file validation checks have been a part of the corresponding csv to binary conversion tools since ktools v3.12.0 (see PR #370). Currently, when using footprinttobin to convert footprint csv files to binary format, there is no check that event ID does not exceed the MAX_INT limit. This can lead to negative event IDs as a result of integer overflow, or even more dangerously positive event IDs that are reported as being 2³² less than that in the csv file.

A check for this should be introduced in a similar fashion to the check on vulnerability ID in vulnerabilitytobin.
