Reads a proving key from a buffer. Does so by reading verification key first, and then deserializing the rest of the file into the remaining proving key data.

Reads a curve element from the buffer and parses it according to the format:

• Processed: Reads a compressed curve element and decompresses it. Reads a field element in standard form, with endianness specified by the PrimeField implementation, and checks that the element is less than the modulus.
• RawBytes: Reads an uncompressed curve element with coordinates in Montgomery form. Checks that field elements are less than modulus, and then checks that the point is on the curve.
• RawBytesUnchecked: Reads an uncompressed curve element with coordinates in Montgomery form; does not perform any checks
