Export `applyFilter` from T.P.Lua.Filter.

Motivation: now we need not have any logic referring to hslua
types (LuaE) in T.P.Filter.Lua.  This restricts the parts of Pandoc
that deal directly with hslua to T.P.Lua (and in tests,
Tests.Lua).

[API changes]

T.P.Lua now exports `applyFilter`, `readCustom`, and `writeCustom`.
The lower-level function `runFilterFile` is no longer exported.
