Subject: [PATCH] Allow multiple Chart files at once

Currently, two calls to chparse.load(file) will return two separate Chart files backed by the same instruments dict resulting in a Chart object that may have incorrect values in the instruments.

Fix this by making instruments part of each instance instead of a class field.
