Thank you to the viewers who pointed out the issue at the

At this point, simple code works, but the conditional
from the joystick input does not seem to work yet.

This change does not affect the generated code, other than the
assembler labels for the data. The data will still be initialized
at compilation time.

Define a constexpr VIC_II::Sprite constructor.

write_multi_color_line(), write_line(): Remove.
VIC_II::SpriteLine<bool multicolor>: A line of sprite bitmap data.
The constructor converts one line of data at a time.
VIC_II::Sprite<bool multicolor>: An array of SpriteLine.
This change does not affect the generated binary code.
In the assembler code generated by clang++-4.0, the binary data
will be formatted in groups of 3 bytes instead of 3*21 bytes.
