Deprecation warnings on installation

Hi to everybody,

would like to use file-saver about I am worried about the deprecation warnings and that npm v8 is there since last week which requires node js v12 and later and on medium term we will have to move to v14.

1. Are you addressing these fsevents and chokidar issues already and when there will be new version ?
2. Insecure binaries : do you have more information about this ? Could that harm my project ?

Using npm version 7.24.2 and node v12.22.3 :
` npm i file-saver
npm WARN deprecated fsevents@1.2.13: fsevents 1 will break on node v14+ and could be using insecure binaries. Upgrade to fsevents 2.
npm WARN deprecated chokidar@2.1.8: Chokidar 2 will break on node v14+. Upgrade to chokidar 3 with 15x less dependencies.
