Adam Rocska 3f4914190d A strategy emerged on how to process MaxMindDB data. May not be the best, but it could work.

Adam Rocska 6449c653b2 It works. The motto should still remain "RTFM". Signed integers arrive as two's complement instead of signed magnitude (duh).

Adam Rocska a9dd03de70 Simplified the inlined type cast state. Now it's time to try the integer sign part.

Adam Rocska bee57f211a Last try before dumping & preconditioning: Moved the typed value contruction into the padding & truncating functions. Here the integer signed cases could be handled properly.

Adam Rocska 438c0eca44 Doing a commit, to save the state. But will remove truncation logic at all, and just simply set a precondition. MaxMind's DB format could possible have an "overflow case" happen, but it just won't be supported.

Adam Rocska 92806b035d I really needed these limitedIndex accessors. I don't know if it's an anti-pattern with Swift or not, but I couldn't find another way around.

Adam Rocska 1f80a1ac6e Syncing github repo with local experiments : 
- Reader now has the data separator defined as is.
- removed dead dummy playground code from MetadataStructTest.swift
- started to work out a last index of concept (naïve one of-course)

Adam Rocska c0dba1887b Committing half made not working code to ask for some help. The search algorithm gets stuck at index 20990 as if it was an overflow, while it can't be an overflow, since it's a typealias for Int, and also, it's not a square number. Weird.
