Manual attribute assignment

Addresses issue #16

This PR simply enables the raw ability to modify the multipage/singlepage tiff class's dimensions from the reader.

Might enable us to manually adjust image dimensions for acquisitions that have been cut short. That condition requires additional testing.

Changing an attribute at the MicromanagerReader level doesn't propogate those changes down into the MicromanagerReader.reader level (the multipage tiff or singlepagetiff reader). I think these need to be propogated downward for the changes to have meaningful impact

When I run the tests here it works. Adding new lines to force it to fail works too:

def test_height(setup_mm2gamma_ome_tiffs):
    _, _, rand_folder = setup_mm2gamma_ome_tiffs
    mmr = MicromanagerReader(rand_folder,
                             'ometiff',
                             extract_data=False)
    orig_height = mmr.height
    mmr.height = 100
    assert(mmr.height == mmr.reader.height) #<-- this passes
    assert(mmr.reader.height == orig_height) #<-- But this fails
    assert(mmr.height == orig_height) #<-- This also fails

Weird, for some reason when I was doing it through the python console in pycharm it wasn't working. I ran your tests and tested it out in a notebook and it worked fine. Definitely a nice feature to have, thanks!
