Combine RX and TX frames into single implementation

[kortemik]

Combine RX and TX frames into single implementation this way writing can be a stateful operation if we transform the arguments directly into the resulting buffer(s) and use a buffer from the pool. This will lessen the need for memory allocation(s).

provide stub as well:

rlp_03/src/main/java/com/teragrep/rlp_03/context/RelpWriteImpl.java

Line 100 in 60da329

// TODO create stub txFrame, null is bad
