Not compatible for running under node.js

[DaveA-W]

v1.0.0-beta.4 relies on the global window object, so will only run in a browser context.
Starting a node.js project that includes the package results in an uncaught exception:

Exception has occurred: ReferenceError
ReferenceError: window is not defined
    at Object.<anonymous> (\node_modules\fast-geotiff\dist\index.js:1:671)
