      xiangjinwu has created [PR #519: feat(extjson): parse legacy `

      {"$date": <ms since epoch>}

      `|https://github.com/mongodb/bson-rust/pull/519] in bson-rust

      Issue Text:
      According to the specification, there exists a legacy Extended JSON form of Datetime
      https://github.com/mongodb/specifications/blob/master/source/extended-json/extended-json.md#datetime
      > Mongoexport 2.4 and the Java driver always transform a Datetime object into an Extended JSON string of the form `

      {"$date": <ms since epoch>}

      `. This form has the problem of a potential loss of precision or range on the Datetimes that can be represented.

      Specially, this legacy form is called `JsonMode.STRICT` in the Java `JsonWriterSettings`, while the canonical form is `JsonMode.EXTENDED`. The former is still used by the Debezium connector for MongoDB.

      This PR adds the ability to parse such legacy format, without conflicting with the standard ones.
