MAINT: Use metadata method for reader init.

Browse Source 
Use the preexisting metadata method when instantiating the minute bar
reader.

An internal sublcass uses the `_get_metadata` method to setup data for
directories that have not used the new writer/reader interface.
(i.e. allows for reader creation when the metadata.json file does not
exist.)
