NEW FEATURE PROPOSAL: ALGORAND MULTI-LANGUAGE PASSPHRASE SUPPORT

[kcelestinomaria]

This is a new feature proposal, to enable multi-language support for Algorand Wallet Passphrases. It was raised as an issue here: algorand/go-algorand#5215 .

This PR needs a review before adoption. Here are the issues:

• I changed the whole mnemonic code structure as it previously was written to default support for English, this has broken some things, and I had to add some helper functions, some unused, so helper.ts, index.ts and mnemonic.ts needs some deeper look and evident refactoring. I changed the typescript files that contained wordlists into json files.
• All languages I added, were based on the most visibly active and large communities on Algorand + most spoken non-English languages on the web.

Is there a more concrete link for the Arabic wordlist? I wasn't able to find the list. Similar remark regarding Indonesian.

Here is where I sorted them from, for Arabic find github repo here: https://github.com/a3f/arabic-wordlists .

I used the Arabeyes wordlist, as the community there had worked on a technical dictionary already with Arabic words, see Arabeyes here: https://arabeyes.org/Download_technical_dictionary . However, as you can see from the Arabic Wordlist repo, there are many other options i.e

• hans-wehr: Hans Wehr's Dictionary of Modern Written Arabic, English version edited by J Milton Cowan
• quran: The Quran in modern Arabic writing style.
• arabeyes: Arab eyes Technical Arabic-English dictionary
• arwiki: The Arabic Wikipedia on 2016-09-20. Not that useful, I guess, because of the many foreign terms and occasional typos
• arzwiki: The Egyptian-Arabic Wikipedia on 2016-09-20
• ar-php: ar-extra-stopwords.txt from the Ar-PHP project

For Indonesian, here is the link: https://github.com/geovedi/indonesian-wordlist . But, as you can see, Google Code Archive shelved the links for the wordlists. I added the Indonesian wordlist for 2011 - Google Code Archive.

Thanks! @tzaffi

I corrected and added concrete links to the files.
One quick question, do you think it is necessary to add entropy functions for the wordlists? Thanks.
