Update read.py

[MDHDZ91]

update the from_cnv reading options to include "prM" without a space as a key, update the prkey error conditional statements to be able to read files that may have more than 1 key (such as both depth and pressure)

Do you have an example file that we can add to the tests? I made a small modification to your PR that hopefully will cover more future cases too.

This is a portion of the .cnv in which I have "prM" a =s my key, that you can use a test.

Thanks! I'll add a test as soon as possible. Do you mind checking if a dev install of the library solves ir for you though? I can cut a release as soon as you do.

calling the updated libraries from my git branch solved my issues, it was really that space in "prM"
