Ran Benita 11f1f79222 Allow creating ExceptionInfo from existing exc_info for better typing 
This way the ExceptionInfo generic parameter can be inferred from the
passed-in exc_info. See for example the replaced cast().

Ran Benita 3f1fb62584 Rework ExceptionInfo to not require manual __init__ call 
Mypy doesn't like calling __init__() in this way.

Ran Benita 14bf4cdf44 Make ExceptionInfo generic in the exception type 
This way, in

    with pytest.raises(ValueError) as cm:
        ...

cm.value is a ValueError and not a BaseException.

Ran Benita 866904ab80 Revert "Let context-managers for raises and warns handle unknown keyword arguments" 
This reverts commit dfe54cd82f.

The idea in the commit was to simplify the code by removing the check
and instead letting it TypeError which has the same effect.

However this type error is caught by mypy, and rather than ignoring the
error we think it's better and clearer to go back to the previous
explicit check.

Ran Benita c1167ac552 Add rudimentary mypy type checking 
Add a very lax mypy configuration, add it to tox -e linting, and
fix/ignore the few errors that come up. The idea is to get it running
before diving in too much.

This enables:

- Progressively adding type annotations and enabling more strict
  options, which will improve the codebase (IMO).

- Annotating the public API in-line, and eventually exposing it to
  library users who use type checkers (with a py.typed file).

Though, none of this is done yet.

Nicholas Devenish 1a8d9bf254 Let approx() work on more generic sequences 
approx() was updated in 9f3122fe to work better with numpy arrays,
however at the same time the requirements were tightened from
requiring an Iterable to requiring a Sequence - the former being
tested only on interface, while the latter requires subclassing or
registration with the abc.

Since the ApproxSequence only used __iter__ and __len__ this commit
reduces the requirement to only what's used, and allows unregistered
Sequence-like containers to be used.

Since numpy arrays qualify for the new criteria, reorder the checks so
that generic sequences are checked for after numpy arrays.
