Benjamin Prosnitz a106defdda hex: fix panic in Decode when len(src) > 2*len(dst) 
hex.Decode never checks the length of dst and triggers a panic
if there are insufficient bytes in the slice.

There isn't document on what the behavior *should* be in this case.
Two possibilities:
1. Error dst has insufficient space (as done in this change)
2. Reduce the length of the decode to min(dst, src)

Option 1 was chosen because it seems the least surprising or
subtle.
