Error in reading VSC in PSSE parser

[jahanbani]

when reading PSSE RAW file version 33 using parse_file, the following error is thrown:
ERROR: KeyError: key "CONVERTER BUSES" not found
Below is an example of the VSC data that generates this error (taken from a PSSE dataset which can be successfully imported to PSSE):

I also tried using PowerModelsData("myrawfile.raw") but got the same error. @scdhulipala
