lxml supports paths already, no modification is necessary there. However, the `lxml.etree.ElementTree.write()` function requires `BinaryIO`, i.e. files opened with the 'b' mode. While it would be possible to access the underlying binary buffer of files opened in text mode via `open()`, this isn't possible for `io.StringIO()`, as it doesn't have the `buffer` property. Thus, even if we could support files opened via `open()` in text mode, we couldn't annotate the XML serialization functions with `TextIO`, as `io.StringIO()` remains unsupported. Because of that, I decided to not support `TextIO` for the XML serialization. The builtin JSON module only supports file handles, with the `json.dump()` method only supporting `TextIO` and `json.load()` supporting `TextIO` and `BinaryIO`. Thus, the JSON adapter is modified to `open()` given paths, while the JSON serialization is additionally modified to wrap `BinaryIO` with `io.TextIOWrapper`. Fix #42
... by using `StringIO` instead of `BytesIO`.

LGTM, that might make the integration of aas-core easier as well. |

However, the
lxml.etree.ElementTree.write()function requiresBinaryIO, i.e. files opened with the 'b' mode. While it would bepossible to access the underlying binary buffer of files opened in text
mode via
open(), this isn't possible forio.StringIO(), as itdoesn't have the
bufferproperty. Thus, even if we could support filesopened via
open()in text mode, we couldn't annotate the XMLserialization functions with
TextIO, asio.StringIO()remainsunsupported. Because of that, I decided to not support
TextIOfor theXML serialization.
The builtin JSON module only supports file handles, with the
