Merge bitcoindevkit/bdk-ffi#215: Add simple kotlin, swift and python integration tests

ee6ee8139afd74c858216ed99ffdec92dc101787 Add simple kotlin,swift, and python integration tests (Steve Myers)

Pull request description:

  ### Description

  Add simple kotlin, swift and python integration tests. These tests confirm fixes in #216 and #214.

  ### Notes to the reviewers

  To skip integration tests use:

  `cargo test --lib`.

  Otherwise java, kotlin, swift, and python need to be installed, and you must run tests with:

  `CLASSPATH=./tests/jna/jna-5.8.0.jar cargo test`

  ### Changelog notice

  - Integration tests added, see tests/README.md for updated instructions for running tests. #215

+# Integration tests for bdk-ffi
+
+This contains simple tests to make sure bdk-ffi can be used as a dependency for each of the 
+supported bindings languages.
+
+To skip integration tests and only run unit tests use `cargo test --lib`. 
+
+To run all tests including integration tests use `CLASSPATH=./tests/jna/jna-5.8.0.jar cargo test`. 
+
+Before running integration tests you must install the following development tools:
+
+1. [Java](https://openjdk.org/) and [Kotlin](https://kotlinlang.org/), 
+[sdkman](https://sdkman.io/) can help:
+   ```shell
+   sdk install java 11.0.16.1-zulu
+   sdk install kotlin 1.7.20`
+   ```
+   
+2. [Swift](https://www.swift.org/)
+
+3. [Python](https://www.python.org/)
