Fix stupid off by one error in Uemis downloader

We are accessing offset 24 in an array of length 24. To make things easier
for the base64 conversion we just treat this as an off by three error and
instead create an array large enough for 27 elements and convert a
sufficient number of base64 chars to initialize all of them.
