Improve Lidax/gwf frame file interface
'LiDaX' is confusing. Nobody knows what it means, or that it can be used to read gwf frame files.
- Handle multiple frame files to provide contiguous data across frames.
- Improve interface in diaggui so that the user can easily tell they can open frame files.
- Improve interface so that the user can easily figure out how to open frame files. Even if you knew LiDaX can be used to open frame files, selecting the frame files is not obvious.
- Bring out any other LiDaX features.
