Wire.write() previously returned the number of bytes requested, even if the
internal 32-byte transmission buffer could not store all of them. This caused
code that paged or chunked writes to prematurely terminate, and silently drop
data.
The function now returns the actual number of bytes appended to the TX buffer,
matching the standard Arduino Wire API behavior and allowing callers to detect
buffer limits correctly.
Fixes #597.
