* Generate a deterministic x & z location based on the randomness in a ULID.
* Generate a deterministic x & z location based on the randomness of an ID.
*
* We'll use the first 20 bits for the x coordinate and next 20 for the z.
* That's a bit over a trillion locations... should be enough for pretty
* unique locations for this fun kind of application within a network
* -- though they're not guaranteed unique without the full ID.
* (We're leaving 40 bits for other properties.)
* We'd like the location to fully map back to the original ID.
* This typically means we use half the ID for the x and half for the z.
*
* ... in this case: a ULID.
* We'll use the first half (13 characters) for the x coordinate and next 13 for the z.
* We recognize that this is only 3 characters = 15 bits = 32768 unique values
* for the random part for the first half. We also recognize that those random
* bits may be shared with previous ULIDs if they were generated in the same
* millisecond, and therefore much of the evenness of the distribution depends
* on the other dimension.
*
* Also: since the first 10 characters are time-based, we're going to reverse
* the order of the characters to make the randomness more evenly distributed.
* This is reversing the order of the 5-bit characters, not each of the bits.
* Also wik: the first characters of the second half might be the same as
* previous ULIDs if they were generated in the same millisecond. So it's
* best to have that last character be the most significant bit so that there
* is a more even distribution in that dimension.
