internal/deephash: increase scratch space size
e66d4e4c8131f89e85f372f6f41ff9580fedf140 added AppendTo methods to some key types. Their marshaled form is longer than 64 bytes. name old time/op new time/op delta Hash-8 15.5µs ± 1% 14.8µs ± 1% -4.17% (p=0.000 n=9+9) name old alloc/op new alloc/op delta Hash-8 1.18kB ± 0% 0.47kB ± 0% -59.87% (p=0.000 n=10+10) name old allocs/op new allocs/op delta Hash-8 12.0 ± 0% 6.0 ± 0% -50.00% (p=0.000 n=10+10) This is still a bit worse than explicitly handling the types, but much nicer.
