+-- @name filePicker
+-- @param bindings A table of the extensions the user can select in the format {{name, ext, a, y},...}, name will show up instead of "File" or "Directory" on the bottom screen, a and y set the action names for those keys on the bottom screen (and also enable them, so if there's neither a or y, the file will have a custom type name but won't be effectively selectable), and ext is the extension to search for, dot included. Everything must be strings.
+-- @param workdir Optional, current working directory will be used if not specified, otherwise, sets the path at which the file browser first shows up, a string.
+-- @returns The absolute path to the file, nil in case no file was picked.
+-- @returns The extension of the file, this might be helpful in cases were multiple file types could be expected, nil in case no file was picked.
+-- @returns The "mode", which indicates which key was used to select the file, "A" or "Y". "X" in case no file was picked.
