citations ending in 'u', continue part 1

[funderburkjim]

This is analogous to #17.

Here, we extend the identification of stems ending in 'u' to those lexnorm-all2 cases where

• the citation ends in 'u'
• the lexnorm is exactly one of
  • f:n 4 cases
  • m:n 51 cases
  • m:f 44
  • m:f:n 1407

This handles about 1500 additional records of lexnorm-all2

After removing duplications, there are additional stems added:

• 1242 additional stems with m_u model
• 1400 additional stems with f_u model
• 1404 additional stems with n_u model.

for a total of 4046 additional stem-model cases ending in 'u'.

There remain 70 records of lexnorm-all2 with stems ending in 'u' which will be accounted for later. Some examples:

2412    aRu aRu m:f#vI:n
14147   amu amu LEXID=pron,STEM=adas
151110  BIru    BIru    m:f#U:f#u:n

The declension of these additional 4046 cases requires no modification to the declension algorithms.
