tests of creating scripts for raster and vector dataset

[Nageshbansal]

Increased code coverage (~5%) by adding tests for creating scripts for raster and vector datasets.

@henrykironde, in my local machine all tests passed because I'm Using GDAL=3.0.2, but here tests are executed with GDAL version 3.2.3, I think we need to change the GDAL version in GitHub workflow.

You could try to change the version and see what happens.

We do have sample raster and vector data. https://github.com/weecology/retriever/tree/main/test/raw_data_gis

So instead of using "https://s3.amazonaws.com/azavea-research-public-data/raster-vision/exam..., you can use our samples.

appveyor is still failing. Looks like it needs a different version of Cartopy. https://ci.appveyor.com/project/ethanwhite/retriever/builds/42411609#L362 https://ci.appveyor.com/project/ethanwhite/retriever/builds/42411609#L366

can we use any other service in place of appveyor for testing in windows

@henrykironde, by mistake I deleted this branch that's why I have to create this branch again and make a PR again.

git hub caches your most of your information. You can recreate the branch using the steps below.

Either :

git checkout -b code-coverage-tests
git reset --hard 71dcdc149
git push origin code-coverage-tests -f

OR:

If that does not work, you can fetch the PR incase you step up the .git/config remote. The docs define how to fetch pull requests.

[remote "upstream"]
    url = https://github.com/weecology/retriever.git
    fetch = +refs/heads/*:refs/remotes/upstream/*
    fetch = +refs/pull/*/head:refs/remotes/origin/pr/*

In this case you can do:

git fetch upstream
git checkout 
git checkout -b code-coverage-tests
git reset --hard origin/pr/1640

can we do one thing, we can close this PR and can continue with PR #1642.
