Filter Read CSV

Iteratively reads in and filters a CSV file based on specified filters.

filter_read_csv(path, batch_size, cols, filters)

`path`	A file path to a local csv file.
`batch_size`	The size of each csv chunk to be read in. If not specified, then the data will be broken into 10 chunks by default.
`filters`	vector of filters to be applied. Each filter should start with the column name and NOT the name of the file; filter_read_csv will take care of this automatically. For example, if one of the filters was to be applied on the column "Age", the filter would be included in the vector as "Age < 40", NOT as "df$AGE < 40".
