[Cryptography] Case-Sensitive letter frequencies

[mok-kong shen]

M. N. Jones and D. J. K. Mewhort have published a table of the counts
and the ranking of the letters, separately for upper-case and
lower-case, from a certain corpus. See
https://www.researchgate.net/publication/8090755

The following is their data of counts together with the frequency
distributions of the letters in the ensemble of both cases.
