Add Validation to Options Parameters to Prevent Handlebars Template Injection

Description

This pull request adds validation to the options parameters in the lib.js file to ensure they are parsed to the correct type and to prevent handlebars template injection. The following changes were made:

• Added helper functions to parse boolean, number, and JSON values.
• Validated and parsed the options parameters using the helper functions.
• Threw validation errors for invalid values to prevent template injection.

Changes

• Added helper functions:
  • parseBoolean(value, paramName)
  • parseNumber(value, paramName)
  • parseJSON(value, paramName)
• Validated and parsed the following options parameters:
  • geojson
  • geojsonfile
  • height
  • width
  • center
  • zoom
  • maxZoom
  • attribution
  • tileserverUrl
  • vectorserverUrl
  • vectorserverToken
  • imagemin
  • oxipng
  • arrows
  • scale
  • markerIconOptions
  • style
  • timeout
  • haltOnConsoleError

Validation Requirements

• Parse strings to correct types.
• Throw error for invalid values.
• Prevent handlebars template injection.

Testing

Manual review of the changes was conducted to ensure there are no syntax errors or obvious logical mistakes. However, there are no predefined test scripts in the project, and the README does not provide instructions for running tests. Further testing may be required to ensure the changes work as expected.
