Add newTable method at Lua interface

[dayo05]

This PR simply adds newTable() method(with default invocation) to Lua interface.

The newTable seems exists on native lua code and highly used on beginner-level code instead its equivalent: createTable(0, 0).

Also, because the LuaNative.newTable exists, its good to add it into interface too.

I just add it via default method of interface because I use github edit page to modify this but if you want then I'll change it to use method inside LuaNative.

Can you please add a tiny test (probably in LuaTestSuite.java)? https://github.com/gudzpoz/luajava/blob/deb4184acf8489cd4b30169672bf256578a4a62b/example/suite/src/main/java/party/iroiro/luajava/LuaTestSuite.java#L918

Something as simple as this will do:

        L.newTable();
        assertEquals(TABLE, L.type(-1));
