Fix download of large files in Console

[reivaj05]

Fixes: #2760

[dvaldivia]

I found a memory problem while downloading a large file, to test this I did the following

1. Generate a 100GiB file via mkfile -n 100g ~/Desktop/LargeTestFile (on macOS)
2. Upload the file via object browser, this completed just fine
3. attempt to download the file, then Safari reset the page due to memory pressure, but I saw the download continues even if the download progress component no longer reports it, after a few zombie connections, it stops al together

on Chrome I was able to download the 100GiB file

perhaps for Safari we can force a direct download? @reivaj05

[reivaj05]

@dvaldivia I believe we won't be able to set anonymous access header if we force a direct download, is that right?

[dvaldivia]

@reivaj05 when do we need to do that? :S

[reivaj05]

@dvaldivia it's part of the existing code: https://github.com/minio/console/blob/master/portal-ui/src/screens/Console/Buckets/ListBuckets/Objects/utils.ts#L54

Added way to download directly in safari if file size is more than 4G

[bexsoft]

Tested the PR with the following scenarios:

• Uploaded 5GB File, everything OK
• Downloaded File in Chrome, Need to find a way to display more constant batches for the progress bar as it updates only every 25%
  
• On Safari, the whole application freezes between batches and sometimes crashes once the download has been completed
  
• On Firefox Navigator Download manager & MinIO's object manager opens at the same time (not really an issue as current behavior opens Firefox manager after MinIO's object manager completes the download)
• On Opera same behavior as Firefox is observed

Tested on Chrome with 4G and 100G files ✅
On Safari I also experienced the same behavior raised by @bexsoft where the app crashes and kind of sends me to the Object browser page. This happens even with 4G files. Small files seem to be working fine.

@bexsoft i couldn't find a better way to display progress, current approach to get the chunks is fileSize/1.5G, i could reduce the chunk size in the code but smaller chunks will translate in more requests to minio and rate limit errors, with 1.5G we avoid the rate limit error

@bexsoft @cesnietor i'm going to let safari browser handle the downloads directly instead of setting a limit because seems 4G files is still too much for safari to handle

Tested in Safari and is download is now being handled by the browser. ✅
