Timeline page improvements

[gameroman]

Describe the feature

• Lower the threshold for decreased dependencies
  I think celebrating improvements is always good so we should reduce the threshold

• For Install size increase/decrease show "previous vs now"
  Currently it says Install size increased by 41% (1.7 MB)
  What I think it could look like: Install size increased by 41% (4.2 MB + 1.7 MB = 5.9 MB) or similar

• If size increase/decrease is >= 3x, show size increased/decreased 3x instead of by 200%

• Show when a specific version of the packages is deprecated

• Celebrate 0 dependencies: if package had even 1 dependency and now it has 0, show that on timeline too

• Add some options to hide pre-release versions, filter by major versions
  Currently it can be confusing:
