[#107] Replace file-embed library with inline config

Problem: At new resolver version we recieved obscure error when tried to cross-compile project to Windows on CI. Changing file-embed version to the old one doesn't help us.

Solution: inline content of this file into haskell source, using raw-string-qq library, that helps us to avoid escaping and typing newline characters.
