debugmergestate: explain why we create mergestate objects directly
We would normally use the read() constructor, but in this case it's fine
because
- we implement our own reading layer, so the extra parsing done by
read() is unnecessary
- read() can raise an exception for unsupported merge state records,
but here we'd like to handle that separately
- debugmergestate needs to be privy to mergestate internals anyway
