The stm32 has a small queue for spi tx/rx. The current code only uses the
spi with a single byte buffer, effectively waiting for each byte to complete
before starting the next transfer.
This patch changes the structure of spi_transfer() to make use of the queue
and achieve back-to-back transfer of bytes on spi.

The current code accesses the DR as 32 bit. This enabled data packing mode,
effectively adding a 00 byte between each sent byte. The receive side had
similar problems.
To prevent this, all accesses are 8 bit now, even though this is not
necessary on stmf[14].

A default config file for Monoprice Mini Delta printers.
Works when firmware is flashed via ST-Link V2 and when a
10A power supply is available. Lots of comments about wanting
to try pressure advance on the FB group, so I figured it was
a good time to get this added.

The default setuptools installed by virtaulenv has dropped support for
python2. Explicitly remove it from the installation.

Move interpolation checks to _init_mesh_params() so they can be done whle the config is being parsed. Do not allow a probe_count higher than 6 for lagrange interpolation, as this typically leads to oscillation.

Don't force probing when BED_MESH_MAP is executed, output the existing mesh. If the user wants to probe each time before a map they can do so with a gcode_macro.

Renamed some variables in set_mesh() previous called "mesh_min" and "mesh_max" to alleviate confusion with the config options.
Renamed several attributes for clarity. The "calibrate" attribute is now bmc, "probe_params" is now "mesh_params", "probed_z_table" is now "probed_matrix", "mesh_z_table" is now "mesh_matrix".

Points are now logged after the printer is ready. The formatting is improved, printing out the point index, and its corresponding automatic and manual points.
BED_MESH_OUTPUT now includes a PGP parameter, if PGP=1 the generated points are printed to the terminal.

Rename min_point, max_point, and bed_radius to mesh_min, mesh_max, and mesh_radius respectively. Add "mesh_origin" option, that allows round beds to specificy the center of the mesh.

Fix typo that resulted in _get_extended_params() being called for all
commands. Allow "extended" g-code commands to contain numbers.

Some kinematics do not result in a constant step rate during homing
operations. Calculate the endstop checking rate using the total
distance traveled on the axis divided by the axis step distance.

The STEPPER_BUZZ command needs to know if the axis is using radians
instead of millimeters so that it can move a more appropriate
distance.

Add a mechanism for obtaining the print_time via a callback instead of
by flushing the look-ahead queue.

The print_time parameter of heater.set_temp() is not currently used
and it isn't necessary to flush the look-ahead queue just get the
print_time. Remove the parameter from heater.set_temp() to avoid
flushing the look-ahead queue.

If a null move is added as the first move on the trapezoid motion
queue then it could have a very large move->move_t value. This could
cause numerical stability issues with some advanced kinematic
formulas. Place a limit on the move_t value to avoid this.
