opcua module

[OutOfBedlam]

This pull request introduces significant updates to the tql module, focusing on integrating OPC UA (Open Platform Communications Unified Architecture) support, improving JavaScript context handling, and fixing minor issues in the codebase. The changes include adding a new OPC UA module, enhancing the JavaScript runtime context, and updating tests to validate the new functionality.

OPC UA Integration:

• Added a new opcua module to the JavaScript runtime, enabling OPC UA client creation and interactions, such as reading node values. This includes support for MessageSecurityModes and TimestampsToReturn. (mods/tql/fm_script_modules.go, mods/tql/fm_script.go, [1] [2]
• Introduced tests for the OPC UA module, including scenarios for reading nodes and handling permissions. A mock OPC UA server is also implemented for testing purposes. (mods/tql/fm_script_test.go, mods/tql/fm_script_test.goR1036-R1225)

JavaScript Context Enhancements:

• Extended the JSContext struct to include context.Context, allowing better control and cancellation of operations within the JavaScript runtime. (mods/tql/fm_script.go, [1] [2]

Dependency Updates:

• Added github.com/gopcua/opcua and related dependencies to go.mod for OPC UA support. Updated several indirect dependencies to their latest versions. (go.mod, [1] [2]

Minor Fixes and Improvements:

• Fixed typos in function and variable names, such as saptial_haversine to spatial_haversine and logx to log_x. (mods/tql/fm_script_modules.go, [1] mods/tql/fm_script_test.go, [2]
• Updated the cspell.json file to include new terms related to the changes, such as opcua, deinit, and EPSG. (cspell.json, [1] [2] [3]

These changes enhance the functionality and maintainability of the tql module, particularly by introducing robust support for OPC UA interactions.
