Add view support for tables with table keys

[robinvierich]

When a table is keyed by other tables, LRDB erroneously reports that the table is empty.

Using "next" on these tables returns JSON and is not parsed into an inspectable lua table.

A simple repro case:

a = {}
b = {}
b[a] = 1

b will be displayed as empty in this case

Hate to resurrect a year old issue but I've just run into this, and it seems to be the case for all non-string table keys.

LRDB/include/lrdb/debugger.hpp

Lines 102 to 107 in 6837898

	if (lua_type(L, -2) == LUA_TSTRING) {
	const char* key = lua_tostring(L, -2);
	json::value& b = obj[key];
	b = to_json(L, -1, max_recursive - 1);
	}

Unfortunately this repo looks a little dead but finding a solution to this seems doable. not mapping lua tables 1:1 to json may be a decent start :p

If you allow for hide by key string duplicates, remove if (lua_type(L, -2) == LUA_TSTRING) and use luaL_tolstring for key.

I think this is a good temporary fix, but it's not really ideal. For table keys that might be fine, but for things like numbers, you probably want to keep that type information somehow.
I recognise that might not fit under the scope of this issue though
