InitSpace does not support tuple structs

[cryptopapi997]

If we try to derive InitSpace on a tuple struct, it will fail with the error Please use named fields in account structure. This is annoying, but the fact that the code seems to intentionally reject this case makes me wonder if there's a reason behind intentionally not supporting this?

Is there one or would you be open to a PR fixing this @acheroncrypto?

It was intentional because Anchor did not support tuple structs during that time. It was added in v0.30 (#2824).

I don't see any reason to not support this, go ahead.
