Gets Config Data

Creates new data table with mfg and mfg PN at the end of current entries

Multiple component vendors
pn (str), multicfg(bool), cfg_qty (str), [ [vendor1(str), mpn1(str)],
[vendor2(str), mpn2(str)]]

Single component vendors
pn (str), multicfg(bool), cfg_qty (str), vendor1(str), mpn1(str)
Added buildConfigs

Wrote buildConfigs which will iterate through all configurations of each
component, generate all build combinations, and combine that with
single-configuration components to generate all BOM lists.
