The `lite` feature doesn't actually disable `regex`

[msrd0]

This is because the lazy-regex-proc_macros crate still depends on regex instead of regex-lite when enabling the lite feature.

I don't think it matters: the complete regex lib is used for compilation but only regex-lite is used in your compiled application.

You can check for example that the binary is much smaller when you use the "lite" feature.

[msrd0]

Well, it might not get included in the final binary, but it definitely increases compile time.

[Canop]

Hum, probably.

The reason I didn't propagate the features into the proc macros is that it complexifies notably its code, for example for the handling of the Bytes variant.

I'll see if I can introduce this without making it too messy.
