This commit changes the method WriteMessage to use bytes.Buffer to save
heap allocations. A unit test is added to check the method is
implemented as expected.
The lnwire package implements the Lightning Network wire protocol.
This package has intentionally been designed so it can be used as a standalone
package for any projects needing to interface with lightning peers at the wire
protocol level.
