  2. Add curve methods for computing y from x & encoding/decoding point 

    Added new methods to `ec_point_fp`:
-  compute_y: solves curve equation y^2 = x^3 + ax + b (mod p) and returns y
-  decompress_point: same as  compute_y but returns point from x and computed y
-  encode_point/decode_point: encodes/decodes point to/from bytes following SEC1-v2 2.3.3 specification
