Bus cost

[csuyat-dot]

2nd PR to #897

On FTA_bus_grant_analyis and tircp_bus_analysis notebooks, was able to clean and add new columns for prop_type and bus_size_type. Also deprecated all the analysis cells as the analysis will be moved to the cost_per_bus_analysis notebook.

On cost_per_bus_analysis notebook, was able to read in both dataset. Calculated a new cost_per_bus column. Updated the summary cells with more descriptive variable names. Consolidated the chart cells by making a function that takes in chart params. Also reworked the statistical analysis (std_dev and z-score) for cost per bus.

However, noticed there were none values in prop_type. Dug into the FTA notebook again and see there are 50+ rows with none prop types that need adjusting (the cleaning step did not account for rows that did not have "( )".)

So far, created a sub-df of only the none value rows, ran it against a list of keywords to replace the none values. Have a couple of rows left to check.

next iteration will remove the none value rows from the initial df, then append the new rows.
