Duplication of terms, periods, etc.

[nandenjin]

Sample case: EB10043(2019) (Thanks for @asagatto777)

The values of terms, periods and rooms are duplicated and they doesn't normalized even in outputs.

Solved with post normalization process.

• Concat consecutive period expressions
• Remove duplication

EB10053 is now "periods":[[[5],[3,4,5]],[[2],[3,4,5]],[[5],[4,5]]] but should be [[[5],[3,4,5]],[[2],[3,4,5]]]. Reopen.
