Research direction

Start at the NewG1FromCompressed entry point and compare its handling of longer-than-allowed input with the behavior described for kilic and gnark-crypto. Determine which behavior the library should guarantee, then add a regression test covering the oversized byte array and verify the resulting behavior.

Written by the indexing model from the issue text.

Description

When supplied with a longer-than-allowed input byte array, kilic will fail after performing an appropriate length check, whereas gnark-crypto will succeed and return a point on the curve.
