Fixes #2706
Fixes #3213

What does this pull request do?

This PR addresses the issue when we import a style with text size or a Number variable with decimal values.

The import of a number like 33.6 is reflected as 33.599... in the corresponding token in the plugin

Also, addresses the number variables imported as NaNrem when the baseFontSize in ui Setting is blank.

Testing this change

• Create a style in Figma with textSize Decimal type or a Number type variable with a Decimal value
• Import in the plugin
• See if the decimal value is imported to the closest 3 places after the decimal
• For the second issue, go to settings and change baseFontSize to blank(thereby setting it to default 16px)
• Import a Number variable with both options of 'Convert Number to dimensions' and 'use rem for dimension values' checked.
• they should no longer be imported as NaNrem token values
