updates to correct spellings in db-01-skdkeys

These are old/new lines of skd.txt.
The coding is slp1.
Based on the corrections from Dhaval
Regenerated, after the db-01-skdkeys corrections
db-01-skdkeys corrections removed. Transliteration slp1

skd.txt was changed to be slp1 encoding.  This was so everything for skd
is now slp1, rather than a mixture of HK and slp1.
lines of skd with 'db<vowel>' (slp1)

Rerun, changing search to slp1 notation
db followed by consonant other than r or y

Redone with slp1 form of skd.txt
lines of skd with db[ry]

Rerun since skd.txt is slp1
Normalization for skd headwords

(a) the data is in slp1 transliteration.
(b)  the final 'M' was left, rather changing to 'm', as before.
