[Feature Request]Add load time and memory display

[LaoshuBaby]

The load time depends on how large the osm file. Usually a 100MB file will cost more than 10s.

To let developer know the improvement between different python interpreter, and don't be too anxiety when waiting for loading, display ETA is needed.

If possible, memory usage also needed.

Just found out, that not all files are large
So if you want to implement dynamic loading, you don't need to display for very small files, they usually complete in a split second

Therefore, we need to set a condition
If the conditions are met, use a progress bar that dynamically adjusts the output content instead

1. Load from the network (no matter how much)
2. Batch loading (at least progress can be determined)
3. Files larger than 100MB (the specific threshold can be negotiated) (it must can't be completed within 1s)
4. It has been used for more than 1s (it seems that although the file is small, it is due to various reasons, perhaps the disk read and write speed, or the processor frequency)
