title: Use different versions of leaflet library
body: <p>I am developing a web application using React and different other libraries.</p>
  <p>I am using Windy API (weather forecast) which uses leaflet library 1.4.0.</p>
  <p>I would also like to use leaflet in the same application but this time using the latest version 1.7.1.</p>
  <p>I import leaflet 1.4.0 with the CDN as described in the Windy API documentation.</p>
  <p>I import the latest version with npm.</p>
  <p>The problem is leaflet is creating a global variable L, so when I import the latest version  of leaflet, the API windy is not working.</p>
  <p>I tried to import leaflet with allias but it doesn't change the problem of the global variable.</p>
  <p>Is possible to change the name of the global variable?
  Any suggestions to solve this problem?</p>
  <p>Thank you !</p>
