Cannot supply constant override if constant name returns digit

[Philogy]

This works:

#define constant LMAO_TOKEN = 0xcccccccccccccccccccccccccccccccccccccccc

Command: huffc -b src/MyThing.huff -c LMAO_TOKEN=0x1079873

This doesn't:

#define constant ERC20_TOKEN = 0xcccccccccccccccccccccccccccccccccccccccc

Command: huffc -b src/MyThing.huff -c ERC20_TOKEN=0x1079873
