Generating bepo layout generates Exception: Too many OEM keys

[gagath]

This seems to be related to the klc Windows generator.
When building the Linux files only, the program exits successfully:

$ kalamine build bepo.toml

    raise Exception("Too many OEM keys")
Exception: Too many OEM keys

The used bepo.toml attached: bepo.toml.txt

Suggestion: the error should be fixed, or at least a clear error message with actionable explanation should be displayed.

Same issue when trying to generate driver for the latest version of Bépolar:

• I got an error saying “Too many OEM keys”
• it traces back to klc driver generation :

[Geobert]

on both instances, removal of the 2 leading spaces on each line of base description fixes the issue

we need to bullet proof the parser
