Implement SOT89 transistor with example and snapshot test

[rushabhcodes]

This pull request adds support for the SOT-89 transistor package to the 3D footprint rendering library. It introduces a new SOT89 component, integrates it into the main rendering logic, updates exports, provides an example usage, and adds a snapshot test to ensure correct rendering.

SOT-89 3D Model Implementation:

• Added a new SOT89 component in lib/SOT-89.tsx that models the SOT-89 package using 3D primitives, including body and leads.

Integration with Footprint Renderer:

• Registered the SOT89 component in lib/Footprinter3d.tsx so it can be rendered when the "sot89" footprint is requested. [1] [2]
• Exported the SOT-89 component from lib/index.ts to make it available for external use.

Examples and Testing:

• Added an example usage of the SOT-89 component in examples/SOT-89.example.tsx for demonstration and manual inspection.
• Created a snapshot test in tests/snapshots/sot89.test.ts to verify the visual output of the SOT-89 footprint.

this part is too wide unlike the reference:

it seems to take a third of the width

Fixed i, was using the wrong width

[ShiboSoftwareDev]

also merge confilct
