ff450497ff add read loops to heif and ppm as well 
We were not looping on vips_source_read() in these loaders, so they
could fail when reading from very slow pipes.

Update Examples.md 
Just some issues I found while testing the examples:
- Reference on header for the file try255.py
- Typo on parameter from bigtif to bigtiff
- Use explicit call to python interpreter from command line

91d9610a55 fix out of bounds read in tiffload 
libtiff can change the value of some fields while scanning a corrupt
TIFF file and this could trigger an out of bounds read.

This patch makes tiffload more cautious about rescanning a TIFF
directory before reading out header fields.
