+- **Spec**: `RB[d]<x>,<y>,<d>`
+- **Description**: A Residual Block with a kernel size of <x>,<y> and a depth of <d>. If [d] is provided, the block will downsample the input. Residual blocks are used to allow for deeper networks by adding skip connections, which helps in preventing the vanishing gradient problem.
+- **Example**: `RB3,3,64` creates a Residual Block with a 3x3 kernel size and a depth of 64 filters.
