ETX-453: Typescript bindings: support package names in commands

[raphael-speyer-da]

• run the "create + fetch & exercise" tests twice, once using package ids in the template ids, and again using package names
• removed some cases where the decoder expected the template id in the response to exactly match the one in the request. Now the request template ids can contain package names, whereas the ones in the response will contain a package id.
• Allow filtering tests in the build-and-lint tests with env var BUILD_AND_LINT_TEST_NAME_PATTERN
