LAS 2.1 reading error

[senovr]

Describe the bug
Hi, I still getting an error while trying to open las file with las version 2.1
Traceback is the following:
las = lasio.read(path_to_las)

KeyError: 2.1

I am aware of a similar bug, that was supposed to be addressed earlier- #29 (comment) , but still getting such error.

Hi! What version of lasio are you using? lasio.__version__

[dcslagel]

@senovr ,

#491 'Add LAS version 2.1 to defaults plus test', just merged to the https://github.com/kinverarity1/lasio master branch and should fix this issue. Would you able to pull the latest, give it a try with the 2.1 Las file, and let us know if it resolved the issue?

Thank you,
DC
