Filenames with special characters need to be handled

[emetsger]

According to the BagIt profile section 2.2.2.1, filenames must not contain characters encoded as:

• 0x00 - 0x1F inclusive
• 0x22
• 0x2F
• 0x3A
• 0x3C
• 0x3E
• 0x3F
• 0x5C
• 0x7C
• 0x7E
• 0x7F
• 0x80 and greater

The OsfContentProvider does not handle the escaping of these characters, which can lead to the production of malformed packages.
