different behavior for bed or bed.gz on bed_to_multivec

Line 19 in c119237

else:

If the file is bed.gz, the lines are read as binary and epilogos/state options work. But if the file is not gzipped, the lines are read as text, and the deafault option works. There is a decode/encode mismatch in the alternative scenarios.
We thought we would leave this issue to you to decide which convention you want to follow.
