Japan and China break the application

[roadmapper]

When Japan or China is selected, the application crashes. This is due to super/subsets of bands being reported in the LTE wiki that the data is scraped from. May need handling for how phones might work with a super/subset of an LTE band (i.e. Band 12 [700 a/b/c] is a superset of Band 17 [700 b/c]).
