KeyError when reading las2 file

[pieterpauw]

Describe the bug
I receive a KeyError when importing a las2 file containing multiple VERS. keywords under different sections (Version Information and
~Parameter Information Block).

To Reproduce
If required, I can share a file. But here is basically the problem:

~Version Information
VERS. 2.0: CWLS LOG ASCII STANDARD -VERSION 2.0

~Parameter Information Block
#MNEM.UNIT Information Description
#---------- --------------- ------------------------
FILE. PROCESSED :File Type
FIID. 9511A :File Type Identifier
VERS. 3.60Q :System Version

Expected behavior

Software versions

• Python version: 3.9
• Python distribution Anaconda
• lasio version 0.31
