Changes
SD Card Bootloader Added Back
We've restored the ability to update your firmware via SD card. Place the appropriate bin file onto the root of your SD card and power cycle the BlueSCSI.
Note you must flash the .uf2 this release to get the boot loader, then use the .bin files for future updates.
Fixes: #77
Present SD Card as USB Mass Storage
Plugging your BlueSCSI into a computer will now present the SD card as a USB Mass Storage device. This allows you to easily copy files to and from the SD card without needing to remove it from the BlueSCSI.
NOTE: The USB connection speed is USB 1.1. This can be disabled via the ini setting EnableUSBMassStorage=false.

USB -> SCSI Bridge Mode
Want to boot your Windows 11 computer off that old SCSI drive? This will allow you to do that.

Present SCSI Images via USB Mass Storage
Instead of presenting the SD card contents, you can present the images on the BlueSCSI to your computer. This allows you to work with files directly on an image. Note: Your computer must support the file system of that image.
Enable it via: USBMassStoragePresentImages=true
Fixes #13

Fast20 20MB/s SCSI Bus Timings
We now support Fast20 SCSI bus timings, which allow for up to 18MB/s transfer speeds.

Buttons on all hardware
Allow users to hook up to two buttons to any BlueSCSI hardware. It will automatically configure them to any removable drives such as CDs. You will can also manually set them if you have more than two removable drives.
Buttons are available on all hardware revs, see Buttons
Interactive USB Console
You can now interact with the BlueSCSI via a USB Serial connection. Currently, the available commands are: reboot, reboot into bootloader, and reboot into USB Mass Storage mode. This is useful for debugging and development. Ideas for new commands are welcome! This replaces PR #215.
