Fix a bug in file geohash/geohash.c
...
Add missing bit shifts in the function geohashstr_to_interleaved in order to be able to calculate correctly the
1) geo coordinates from a given geohash and
2) neigbor geohashes of a given geohash.
The incorrect calculation of neighbor geohashes e.g. has the following impact on the deduplication with lieu: Features are compared that should not be compared because they are too far away from each other. This often results in distances between duplicates that exceed by far the max. expected distance according to the used geohash precision.

[expand/dedupe] expansion with multiple languages (or multiple predicted languages) can sometimes produce weird string trees and thus either too many results or incorrect results, particularly for root expansions which we depend on for matching/deduping. Making one call per language identified. This may slightly affect performance on languages that are highly ambiguous (even that's doubtful, as libpostal usually identifies one or two languages with high accurracy and/or people are using a known geography) but should improve the results and was simpler implementation-wise than trying to use the single single string tree for multiple languages where, say, a two word phrase in one language might simply be token-space-token in another.

[build/fix] using Github for the model releases rather than the Mapzen S3 buckets which are no longer working after the shutdown. It requires a little more effort to get the metadata, but downloads should still be just as fast since Github releases are on S3 as well. Note: still need to implement the upload piece, but this at least provides a model endpoint for users.

[fix] DICTIONARY_STREET_NAME applies only to the street component, unlike synonyms, which would apply to any compnoent. This makes street names a good place to add synonyms found in streets that are not exactly thoroughfare types i.e. could not be removed from the string and have it retain more or less the same meaning.

[dedupe] with some term weighting schemes (especially information gain which will soon be the default in the lieu project), single letters may have very low weights such that they will be discarded, which can lead to false positives for things like "A & B" vs. "B & C", so add a simple heuristic to simply demote likely dupes to needs review when there's a positive symmetric difference (or whatever the set theory term is for when A - B and B - A are both non-empty)

[dedupe] in the case of abbreviations and acronyms, where we use the higher of the two scores, calculate an offset to the norm of the other string's scores i.e. sincey we're replacing the score(s) in the lower-scoring vector with the higher one in the dot product for the numerator, do the same for the L2-norm product in the denominator. This way we don't accidentally inflate the similarity value simply because e.g. an acronym token was more rare than the same acronym spelled out as multiple individual letters (tend to be low-information/common tokens).
