Memory leak when verifying RSAPSS signature

[zhengyao-lin]

Hello! I seem to be getting a memory leak issue at this line:

libcrux/src/signature.rs

Line 188 in b2b9c4e

let pkey = Hacl_RSAPSS_new_rsapss_load_pkey(

, where the allocated pkey is never freed.

Thanks for spotting this! We are in the process of dropping the C code.
So this should go away as part of #537. The code will be replaced in #703.
