Provide curve names as header row in ~A line
Provide an option in LASFile.write
to put curve names in the ~A row.
This is related to #30 and #90 which address reading this kind of data in.
What is the desired behaviour?
For this input LAS file:
~Curve Information
DEPT.M : 1 DEPTH
CALI.mm : 2 CALIPER
DENS.g/cc : 3 DENSITY
Gamm.CPS : 4 Gamma
~Parameter Information
~Other Information
~A
0.05 -0.0 -0.0 -0.0
0.10 -0.0 -0.0 -0.0
You would be able to do las.write(..., mnemonics_header_row=True)
:

Edge cases to be handled with regression tests
- [ ] where mnemonics are missing from the ~C section, there should be the appropriate lasio-generated
UNKNOWN
mnemonic in the ~A header row only (not in the ~C section) - [ ] where duplicate mnemonics exist, the ~A header row should contain these as duplicates, NOT the lasio-generated
GAMM[1]
,GAMM[2]
etc with suffixes - [ ] where mnemonics are longer than the specified write fmt, the width of the column in the data section will need to be increased to cater for the increased length of the mnemonic
- [ ] when the data section is wrapped, specifying
mnemonics_header_row=True
should revert to False, and a logger.warning call made to inform the user/application that this doesn't work.
