[Tasks] Repository migration

[syoyo]

We've moved the repo from syoyo/tinyobjloader to tinyobjloader/tinyobjloader.

Need to sync/update this change for linked third party services

• Travis https://travis-ci.org/tinyobjloader/tinyobjloader
• Azure pipelines https://dev.azure.com/tinyobjloader/tinyobjloader
  • Set API Token from PyPI repo to TWINE_PASSWORD env var
  • automate build binary wheels(cibuildwheels) and twine upload for each tag:
• AppVeyor
  • https://ci.appveyor.com/project/syoyo/tinyobjloader-6e4qf/branch/master
• Coveralls(deprecate it)
• Conan(deprecate it) : Remove bintray and conan build since these are not maintained anymore. #317
• PyPi
  • [x]
• Bintray(deprecate it) : Remove bintray and conan build since these are not maintained anymore. #317
• gitter(deprecate it)

@paulmelnikow Set up Azure https://dev.azure.com/tinyobjloader/tinyobjloader and invited you to there. Please confirm if you have enough permission on Azure Pipelines

[paulmelnikow]

I don't seem to have any special access to the organization in Azure Pipelines. Could you try to invite me again? I'm sending you an email from the email address I use there.

@paulmelnikow Added your email to Azure Pipelines

[paulmelnikow]

I see it now, thanks!

bintray(and conan) build is not maintained anymore and removed soon by merging this PR : #317

[syoyo]

Last thing: Drop coveralls support.
