Implement Vtc File

NF: implement read and write for BrainVoyager QX VTC files

NF+RF: implement read and write support for BrainVoyager QX MSK files and refactor bv.py

NF: implement read and write support for BrainVoyager QX NR-VMP files

TST: add test data for BrainVoyager QX files (VTC, MSK, and NR-VMP files)

RF: create additional CArrayProxy class to work with C array memory layouts.

RF: BvFileHeader inherits from LabeledWrapStruct

BF: implement default_structarr for VMP files; NF: implement new set_shape method (with alternative propoerty zyx) for BrainVoyager file formats

NF+BF+RF+TST: major refactor of BV formats implementation. Add tests for BV formats. Add affine for BV formats.

RF: change side effect of update_header methods

NF: VMP files can change shape (with _add_submap and _rem_submap)

BF: change default values for vmp submaps; look for value (instead of key) when setting a string in the header

BF: save old hdr when for transferring keys when changing the number of maps

BF: change dtype of RGB fields to u1

BF: correct they way that nested dtypes of strings (length) are changed for VMP files

BF: default_structarr for VMP header fills map1 and not map2

BF: in __setitem__ check for basestring; remove setString method

NF: Implement basic support for some BrainVoyager QX file formats.

This is a squashed commit for implementing basic BrainVoyager QX files support. See below for the single commit messages.

First implementation. Copy of LabeledWrapStruct without inheritance.

RF+TEST: Change the header parsing for BV file formats and implement tests.

The BV file headers are now parsed using an OrderedDict. Tests are implemented
for VtcImage. Only the VtcImage class is adapted to the new header parsing.

DOC+PL+RF: Adding documentation and linting to bv.py. Let readCString return
a list instead of a generator.

PL: Removing blank lines.

RF: Simplify and centralize the bv hdr prototype.

Header prototypes are defined per BV filetype as nested tuples. The creation
of an OrderedDict header is done centrally for all filetypes in bv.py
based on these prototypes.

WIP: separating prototype and default header

Refactor the prototype format to make it a little easier to use.

Pass the prototype into functions working with the header, to provide
read / write format information.

Return headers with (key, value) pairs, where the `value` is a value or
a list, rather than a dict.

WIP: Adapt BV MSK file implementation to new hdr.

STY: flake8-compatible code.

RF: move files into brainvoyager subdirectory.

STY: Prepend "Bv" to all brainvoyager classes.

BF: merge new protoHeader implementation into refactored bv files.
