P5 screens in chains, 3.0.9 and 3.0.10 horizontal misalignment #609

When I installed version 3.0.10 I noticed a horizontal shift when the screens are connected in chains (2x2), the same is with version 3.0.9., on 3.0.8 everything displays correctly. Chip FM6124D

p.s. great library, big thanks to the author.

Now I see that this problem could be Issue "2: Vertical output isn't aligned", I will test tomorow.

UPDATE: With added line in setup "mxconfig.clkphase = false;" everything sorted out, there is only typing error on page https://github.com/mrfaptastic/ESP32-HUB75-MatrixPanel-DMA/issues/134, in Issue 2 is written solution "mx_config.clkphase = false;" when it should write "mxconfig.clkphase = false;"

Yeah. I changed the default as having it the other way caused issues with more than 50% of the users of this library.
