Improved support for Access 2010, 2013, and 2016

Browse Source 
Some Access 2010 files use 0x03 as the version number rather than
0x0103. For this reason I have changed the call to mdb_get_int32 to
mdb_get_byte.

In addition, according to the Library of Congress page:

https://www.loc.gov/preservation/digital/formats/fdd/fdd000463.shtml

Access 2016 uses 0x05 as the version number. I have inferred from the
Wikipedia page that Access 2013 likely uses 0x04.
