Allow Digiline Filter-Injector to match wear, metadata, and group

You can now make reqyests like `{group="stick"}`, `"default:pick_wood 1
30000"`, and `"mod:block <count> <exact wear> <meta>"` to match
items precisely.

If you don't specify a field, that field won't be checked.  If you
specify a field in an invalid way, that rule will match nothing.

You can also specify wear as a table `wear={min, max}` to specify
a range `[min, max)` of acceptable wear values.  For example,
`{name="default:pick_wood", wear={0, 32768}}` matches only wooden
pickaxes that have at least half of their life left.

You can even do things like `{count=2, metadata="whatever")}`, which
will match any item at all, as long as its metadata matches, and will
retrieve at most two of those items.
