Alex Akselrod 55e693aa09 zpay32: fix decoding when payment request is too short 
This commit fixes a panic that can result when a zpay32 payment request
that is too short (and possibly invalid) is attempted to be decoded.

To fix this bug, we now simply ensure that that after we decode the
zbase32 encoding, the resulting set of bytes is _exactly_ the length we
expect. A new error has been introduced to handle this case, and a
simple test has been added which ensures proper handling of short
payment requests.

Fixes #127.

[Build Status] (https://travis-ci.org/lightningnetwork/lnd) [MIT licensed] (https://github.com/lightningnetwork/lnd/blob/master/LICENSE) [GoDoc] (http://godoc.org/github.com/lightningnetwork/lnd/zpay32)

The zpay32 package implements a basic scheme for the encoding of payment requests between two lnd nodes within the Lightning Network. The zpay32 encoding scheme uses the zbase32 scheme along with a checksum to encode a serialized payment request.

The payment request serialized by the package consist of: the destination's public key, the payment hash to use for the payment, and the value of payment to send.
