DRAFT: Proper word alignment for translation

[valgardg]

The previous (current) solution to Icelandic -> English word translations is to iterate through each word and translate them one by one. This has several disadvantages

• Because its a per word translation, the context of the word within the overall sentence is lost and translations lose meaning and are often incorrect
• AWS translation API is currently used for translation and while translating whole sentences is good enough, per word translation is severely lacking and provides inaccurate / incorrect and sometimes nonexistent translations which are counterproductive to the goals of the webapp

This pull request aims to add better translation for each word by leveraging the use of a fine-tuned word alignment model to align each source sentence word to its translated target sentence equivalent
Model fine-tuning was done using awesome-align (https://github.com/neulab/awesome-align)
