Feature Request: LoadTableFromString

[klepto2]

currently i only find LoadTable functions for a path or a stream, it would be nice to have a method to load the table structure by providing just a json string (eg: When Fetching a url request) 

In general this can be done by using the Stream method, but the stream override is not available in lua and might be a bit complicated to use.

LoadTable will now return a Lua table from a string as well, if it is encased in {} or [] characters.

Note that type(t) will now be "table" instead of "userdata".
