libtiff's default stripsize is tiny (8KB), so splitting the image into
such strips on writing would significantly hurt the compression
rate. Aim for 4MB strips instead.

When writing an image without compression, libtiff will automatically
store it in strips of default size, and add a ROWSPERSTRIP tag
accordingly. However, if compression is enabled, libtiff does not do
this. The lack of this tag may create trouble for readers.
Fix by explicitly setting the tag in all cases.

In lossless mode, libwebp interpretes the quality setting as a
compression-effort setting instead. The code used to set it to 100
(maximum), which could lead to unreasonable compression times (several
seconds for a small image). Instead set it to libweb's own default value.

Also, since the alpha channel compression has its own quality setting,
make sure it follows the main quality/effort setting.

Webp files can be with or without alpha channel. The handler would
ignore this and read all as Format_ARGB32 images, and write all as
having alpha, in both cases losing that important bit of information.

As a driveby, simplify the endianness handling in write(). By always
converting the source image to an endianness-independent QImage
format, no special handling is required.
