🚀 Added
PLC Modbus TCP Block
This new block brings Modbus TCP communication to Workflows. The block uses the pymodbus library to read from and write to PLC registers over Modbus TCP. It supports three modes of operation:
read: Reads specified registers from a PLC.
write: Writes specified values to PLC registers.
read_and_write: Performs both reading and writing operations in one execution.
Adding Modbus TCP support allows workflows to interact with a broader range of PLCs and industrial devices that use the Modbus protocol.

Velocity block
New analytics block was added to Workflows to calculate and embed velocities and speeds of tracked objects across video frames.
Key Features:
- Velocity Calculation: Computes raw and smoothed velocities based on object movements between frames.
- Speed Calculation: Determines the magnitude of velocity vectors to obtain speed.
This block supports smoothing of velocity measurements using an exponential moving average with configurable smoothing_alpha.
Incorporated unit conversion from pixels to meters via the pixels_per_meter parameter

Add support to run ResNet Classification Model in Inference
The recent update to the Roboflow Inference repository introduces support for ResNet classification models, as described in the seminal paper "Deep Residual Learning for Image Recognition" (He et al., 2015, [arXiv:1512.03385](https://arxiv.org/abs/1512.03385)). This integration enables users to leverage the powerful ResNet architecture for image classification tasks, enhancing the model options available within the inference engine and expanding its utility for diverse computer vision applications.
