Add support for flatbuffers>=2.0

[stancld]

Hello all 👋

First of all, I'd like to thank you for this great repo and package!

I would like to ask you if there's any plan to add support for flatbuffers>=2.0 in a perceivable future? :] Also, if interested, I'm definitely willing to give a try to handle these breaking changes and try to accommodate supports for both versions (It looks like there are some breaking changes between versions 1.12 and 2.0).

Oh, sorry for the false alarm. It's rather an issue of TF itself. :]

tf 2.10 switched to flatbuffers 2.0 so we should reopen this

When installing:

ERROR: pip's dependency resolver does not currently take into account all the packages that are installed. This behaviour is the source of the following dependency conflicts.
tensorflow 2.10.0 requires flatbuffers>=2.0, but you have flatbuffers 1.12 which is incompatible.

@fatcat-z Thanks a lot for the fix! 🚀
