* (a[len-1] & 0x7F) + sum(i=1..len-1, 128^i*((a[len-i-1] & 0x7F)+1))
*
* Properties:
* * Very small (0-127: 1 byte, 128-16511: 2 bytes, 16512-2113663: 3 bytes)
* * Every integer has exactly one encoding
* * Encoding does not depend on size of original integer type
* * No redundancy: every (infinite) byte sequence corresponds to a list
* of encoded integers.
