e57 /ptx loading issues

These two bugs were submitted by email, so I am adding them here for the benefit of other testers.

Error importing e57:

“guess_csv_delimiter: The input file “XXXXXXX.e57” had a non-terminated quoted column data entry.”

and error importing ptx

“ptx_particle_istream: While reading “XXXXXXXX.ptx”: Unexpected number of columns in particle 10966627. Expected 4 columns, but got 1 instead.”

Thanks for the report and please report any issues or unexpected behavior that you encounter!
