sovol sv01 bltouch mount

The original remix has been modified with holes for countersunk screws and reinforcement.

Here are the probe mount point values used on my machine
x_offset: -33.5
y_offset: -2

These values were made by eye after mounting on the machine, but they work well.

At the above mount points, if the bed is 220x220, the mesh will look like this
mesh_min: 2, 5
mesh_max: 185, 218
