This encoding and encodings like it are not uncommon. DWARF uses it, for
example, although with the other endian-ness (it's called ULEB128 or
SLEB128 there depending on whether it's unsigned or signed). UTF-8 uses
a variation, with two flag bits instead of one, but I don't think it has
a name.

Since DWARF calls it LEB128, one could reasonably call this encoding
UBEB128 (unsigned big-endian base-128).
