libsecp256k1 0.3.2

This release fixes a "constant-timeness" issue in the ECDH implementation with GCC >=13 that could leave applications using libsecp256k1 vulnerable to a timing side-channel attack. We strongly recommend any users of the library to upgrade if their code may end up being compiled with an affected version of GCC.
