Describe the bug
For some big LAS 3 files reading is very long.
This is due to the regex in lasio/reader.py that searches "_Data" in the section title but in my example the section is "XXX_DATA".
Btw by using this regex it is very fast. Could you implement it ?

[...]elifre.search("_data",stitle.lower()):return"Las3_Data"[...]

To Reproduce
I cannot provide my files for confidential reasons but :
Take a las file:

• with YOURKEY_DATA delimiter for data section
• large amount of data (10k+ lines)

You will see that atm it takes a lot of time.

Expected behavior
Reading should last only a few seconds

Software versions (please complete the following information):

• Python version: 3.10
• Python distribution: conda
• lasio version: 0.31
