Dear @twistedfall, @samoylovfp, @hdhoang,

Kindly requesting to re-license your work in serde-rustsqlite under MIT or Apache-2.0, so that the users of Burn project can distribute binaries. Please see #21 for more details.

[samoylovfp]

Permission is hereby granted by me (samoylovfp) to re-license the changes I have made to the source code of this project (serde_rusqlite). My contributions can now be licensed under MIT AND/OR Apache 2 licenses.

Thank you for maintaining this project.

[twistedfall]

Let's wait for another confirmation and I'll merge this, thanks for making the effort for this PR

[hdhoang]

I (hdhoang) dedicate my contributions in this project to the public domain, and hereby disown any and all copyright on them.

Wish you all lucks.

[twistedfall]

I have released version 0.34.0 with that change (and rusqlite bump)

@twistedfall Than you very much!
