bugs with uproot and Delphes interactions

[kratsg]

>>> import uproot
>>> uproot.__version__
'4.1.1'

A simple script like the following will confirm bugs on both of these files:

import uproot
with uproot.open('test.root:Delphes') as tree:
  tree.arrays(entry_stop=1)

which either results in one of two different errors (depends on Delphes versions... and what process is generated...)

bug in fBits counting, but might be a header interpretation issue somehow

ValueError: When changing to a larger dtype, its size must be a divisor of the total size in bytes of the last axis of the array.
