I added support for SoLE and SoLD tagged_blocks. This includes support for object arrays.

I wrote the code to parse object arrays and tried to make a more useful SoLD and SoLE tagged_block. I also added support for getting the transform points and the original size of the layer (smart object) from the user api. 

I tried to created a test and did. It seems to run fine but I cant run all the tests because py.test is breaking for me... It also seems to be breaking here. I didn't touch any of that code though and it doesn't make sense why it would be failing now.

tests/test_pixels.py::test_composite[filename8-point8-color8-get_color1] PASSED
tests/test_pixels.py::test_composite[filename9-point9-color9-get_color0] PASSED
tests/test_pixels.py::test_composite[filename9-point9-color9-get_color1] PASSED

Anyways this code is something I wrote for a feature I need to access smart objects and their true sizes. 
According to pep8 there should be 2 blank lines between class definitions - let's keep them!
