/* BOLT#07:
*
* The `short_channel_id` is the unique description of the funding
* transaction. It is constructed as follows:
* 1. the most significant 3 bytes: indicating the block height
* 2. the next 3 bytes: indicating the transaction index within the block
* 3. the least significant 2 bytes: indicating the output index that pays to the channel.
*
* The standard human readable format for `short_channel_id` is created
* by printing the above components, in the order: block height,
* transaction index, and output index. Each component is printed as a
* decimal number, and separated from each other by the small letter
* `x`. For example, a `short_channel_id` might be written as
* `539268x845x1`, indicating a channel on the output 1 of the
* transaction at index 845 of the block at height 539268.
