Allow passing special value to indicate that masked summarizers should select any bin>=0

[joezuntz]

Problem & Solution Description (including issue #)

This allows passing the string "all" as the selected_bin configuration option to the NaiveStackSummarizer and PointEstHistMaskedSummarizer classes. In that case any non-negative tomographic bin index objects will be selected, allowing us to run a non-tomographic analysis alongside a tomnographic one without duplicated data.

Code Quality

• My code follows the code style of this project
• I have written unit tests or justified all instances of #pragma: no cover; in the case of a bugfix, a new test that breaks as a result of the bug has been added
• My code contains relevant comments and necessary documentation for future maintainers; the change is reflected in applicable demos/tutorials (with output cleared!) and added/updated docstrings use the NumPy docstring format
• Any breaking changes, described above, are accompanied by backwards compatibility and deprecation warnings

Would it make sense to use "-1" to mean all to avoid mixing types?

[joezuntz]

I have updated to define constants in common_params.py for doing no tomography (the existing -1 value) and using all non-negative bins (a new -2 value), and use these in the PR.
