python-ijson-3.0-bp155.2.12

- update to 3.0
  * Exposing backend's name under ``<backend>.backend``,
  and default backend's name under ``ijson.backend``.
  * Exposing ``ijson.sendable_list`` to users in case it comes in handy.
  * Improved the protocol for user-facing coroutines,
  where instead of having to send a final, empty bytes string
  to finish the parsing process
  users can simply call ``.close()`` on the coroutine.
  * Including C code in coverage measurements,
  and increased overall code coverage up to 99%.
  * Full re-design of ijson.
  * Initial support for ``asyncio`` in python 3.5+.
  * Exposure of underlying infrastructure implementing the push model.
  * C extension broken down into separate source files
  for easier understanding and maintenance.
  * Fixed a deprecation warning in the C backend
  present in python 3.8 when parsing Decimal values.
  * New `kvitems` method in all backends.
  Like `items`, it takes a prefix,
  and iterates over the key/value pairs of matching objects
  (instead of iterating over objects themselves, like in `items`).
  * When using python 2, all backends now return
  `map_key` values as `unicode` objects, not `str`.
  * Including more files in source distributions (#14).
  * Adjusting python backend to avoid reading off the input stream
  too eagerly (#15).
