"Compliance" ideas

The philosophy of lasio has always been that it should try and load even the ugliest of poorly-formatted LAS files. Anything is better than errors. The flip side of this is that the standard continues to be ignored. It might be possible to add features to lasio which enable it to keep track of the lines in the file which might cause issues with other less flexible software. It is the "compliance" function.

I have no desire to write a formal program to check if a file is compliant, as they are already out there, and I'm not that interested. But it would be nice to provide a place in the module where people can see which lines have been "dodgy" and where lasio has gone to effort to pull in something useful, but where other software might not.
