sr_taxlots_2

[asi212]

The following changes to sr_taxlots_2 were made

1. Added init into account folder
2. Added line 216 in ledger.py to account for floating imprecision
3. Moved self.date_index += 1 down to line 391 (previous position) to maintain proper loop behavior
4. added reward variable to initialization of def return_terminal in env file
5. Added "total_assets" to the ledger
6. Rewrote/changed def save_asset_memory and def save_action_memory in env to function with new ledger and return account_value dataframe that is used with the backtesting functions

*Note: also see comment on line 97 in ledger.py. I believe the order of variables in the subtraction operation may be reversed? I did not make a change yet though.
