* A node MUST use the formula 338 + 32 bytes for every non-dust HTLC as the bytecount for calculating commitment
* transaction fees. Note that the fee requirement is unchanged, even if the elimination of dust HTLC outputs
* has caused a non-zero fee already.
* The fee for a transaction MUST be calculated by multiplying this bytecount by the fee rate, dividing by 1000
* and truncating (rounding down) the result to an even number of satoshis.
