Update tile URL for HERE traffic

[omartijn]

This fixes 400 errors when trying to use HERE traffic tiles with a newer account. The old URL was deprecated and only works in older accounts.

Note: I do not have access to an old account and I cannot be sure that this works correctly for old accounts. Please test this before merging.

Thank you very much! I will review it in the next few days. Note that tools subfolder has some scripts that may help with HERE languages maps generation.

it looks to be mostly working except if you use mar default language: local. In this case, lang=mul is added to URL and I am getting errors (400) with a message

  "details": [
    {
      "message": "The 'lang' parameter in 'query' has an error: string doesn't match the regular expression \"^[a-z]{2}(-[a-zA-Z]{1,4})?$\""
    }

I wonder what is the analog of mul in the new API? This is using old account

PS: sorry for delay!

Well, according to the Migration Guide they now use BCP 47, it mentions the following:

The 'mul' (Multiple) primary language subtag identifies content in multiple languages. This subtag SHOULD NOT be used when a list of languages or individual tags for each content element can be used instead. For example, the 'Content- Language' header [RFC3282] allows a list of languages to be used, not just a single language tag.

I cannot find another suggestion as to what to use. I guess you want to use this to get the native names (i.e. the ones local to what you are looking at). I think Pure Maps should get the language code for the country being viewed here.
