Reduce (part of) dates already present in generic entries from MHDB

[Marinovsky]

Description

For each entry of the markets CME, CBOT, NYMEX, COMEX, OANDA, HKFE and SGX, I removed the holidays, early closes, late opens and bank holidays that were already present in its generic entry (the ones ending with [*]). The following files contain, for each market and for each entry, the dates that were removed.
sgx_hkfe_logs.log
oanda_logs.log
comex_logs.log
nymex_logs.log
cbot_logs.log
cme_logs.log

How Has This Been Tested?

I used the method check_disjoint_holidays_with_parent from the following python module (https://github.com/Marinovsky/LEAN-MHDB/blob/master/main.py#L523) to find and remove those redundant dates automatically.
