This commit updates the godocs for the package, and adds an optimization
to the privkey.Pubkey() method.
The optimization is that in golang, the private key (due to interface
compatibility reasons) has a copy of the public key stored inside of it.
Therefore if this copy has already been computed, there is no need to
recompute it.
Currently the top level directory contains basically all of the code
for the crypto package. This PR moves the crypto code into submodules
in a similar manner to what `golang/x/crypto` does. This improves code
organization.

except now we calculate the max size using the maxPacketMsgSize()
function, which frees developers from having to know amino encoding
details.
plus, 10 additional bytes are added to leave the room for amino upgrades
(both making it more efficient / less efficient)
