Latest anchor version is incompatible with solana 1.16.x

[ellttBen]

In the latest version, anchor_lang is incompatible with solana-program 1.16.x due to https://github.com/coral-xyz/anchor/blob/970cd236b60ca5b814abdfae8fa0227ada4d15bf/lang/src/lib.rs#L204. The ArithmeticOverflow variant was added in 1.17.x. The dependency should therefore be bumped to 1.17 to avoid these kinds of issues.

Yes, unfortunately I realized this after making the release, but it shouldn't be a big deal since most projects are going to need the 1.18 version anyway due to other dependency compatibility issues.

Thanks for bringing this up, I'll bump it before the next version.
