Add a LICENSE file

[mmsaki]

Hi, and thanks for maintaining this — the per-make trouble-code data is genuinely hard to find anywhere else in a usable form.

The repository doesn't currently declare a licence, and GitHub reports it as NOASSERTION. Without one, the default position in most jurisdictions is all rights reserved, which makes the data risky to depend on even where you'd clearly be happy for people to use it.

Would you consider adding a LICENSE file? Two that fit this kind of dataset well:

• CC0 1.0 or ODbL if you think of it primarily as data
• MIT if you'd rather it match the tooling around it

Happy to open a PR adding whichever you prefer.

For context: I ship an iOS diagnostics app that reads OBD-II trouble codes, and obdb is the source I'd like to credit for the definitions. Right now I can credit the project but can't state the terms, which is the part I'd like to get right.

Hi for the interest !
for your app the license allow use of the data with the mention in credits:
Contains information from AutoDiag2 Database, available under the Open Database License (ODbL) 1.0.
with a link to the repository and ODbL license.

There is not an obvious requirement that your entire iOS application become GPL or ODbL merely because it uses the data.

github NOASSERTION is because automated license parsing fail because license is custom (GPLv3 for code, ODbL for the data)

Thank you @autodiag2 noted!
