Sets the form how EC::Point data is encoded as ASN.1 as defined in X9.62.

format can be one of these:

:compressed: Encoded as z||x, where z is an octet indicating which solution of the equation y is. z will be 0x02 or 0x03.
:uncompressed: Encoded as z||x||y, where z is an octet 0x04.
:hybrid: Encodes as z||x||y, where z is an octet indicating which solution of the equation y is. z will be 0x06 or 0x07.
