Update internal swagger-codegen-cli to 3.0.63

[fanalin]

Hi,

this PR updates the swagger-codegen-cli to 3.0.63. The newer swagger-codegen-cli fixes a lot of bugs.
The jar file was simply downloaded from maven central https://repo1.maven.org/maven2/io/swagger/codegen/v3/swagger-codegen-cli/3.0.63/swagger-codegen-cli-3.0.63.jar - there is also a checksum file to check the correctness of it.

Please consider accepting it and release a new version. TIA

Best regards
Matti

If anyone else is stuck because this package has not been updated for a while, here is how to replace the binary automatically :
in package.json add a new postinstall script

{
  "scripts": {
    "postinstall": "./scripts/postinstall.sh"
  }
}

Create an executable script in scripts/postinstall.sh with the following content:

# download version 3.0.64 (latest) of swagger-codegen-cli and write it in the node_modules for swagger-nodegen-cli
curl -sS https://repo1.maven.org/maven2/io/swagger/codegen/v3/swagger-codegen-cli/3.0.64/swagger-codegen-cli-3.0.64.jar --output $(dirname "$0")/../node_modules/swagger-nodegen-cli/bin/swagger-codegen-cli-3.0.34.jar

This script will re-download the file every time you install your node modules.

This repo is the official release for the binary. Check it if you want to update further versions and replace 3.0.64 in the curl command.
