tvg saver is a new module to export tvg files.
In this patch, it also contains the infrastructure of saver module
to expand other types of savers such as png, jpg, etc.
To save the tvg file from a paint, you can use the Saver feature, for example:
auto saver = tvg::Saver::gen();
saver->save(paint, "sample.tvg");
saver->sync();
Later, you can read the "sample.tvg" using Picture.
auto picture = tvg::Picture::gen();
picture->load("sample.tvg");
...
The behavior of the saver will work on sync/async based on the threading setting of the initializer.
Thus if you wish to have a benefit of it, you must call sync() after the save() in the proper delayed time.
Otherwise, you can call sync() immediately.
Note that, the asynchronous tasking is depent on the saver module implementation.
Also, you need to enable tvg saver/loader modules from meson option. (yet this feature is under the beta)
@API Addition:
Result Saver::save(std::unique_ptr<Paint> paint, const std::string& path) noexcept;
Result Saver::sync() noexcept;

* svg_loader: allow both clipPath and mask together
* svg_loader: allow both clipPath and mask together fix#1
Changed seperate functions _applyClipPathComposition and _applyMaskComposition into single function _applyComposition
replace from ofstream to FILE
We know both have the same purpose, we always prefer the less binary size.
So... this brings the binary size reduction.

Previously the 'test.tvg' file was loaded from the EXAMPLE_DIR.
Now the 'test.tvg' file is created using the tvg saver module
(if in the EXAMPLE_DIR is alread a 'test.tvg' file, it is overwriten)
and then it's loaded using the tvg loader module.
The Saver class enables to save any Paint object (Scene, Shape, Picture)
in a binary file. To read the file the tvg loader should be used.
To save a paint a new API was introduced - tvg::Saver::save.
For filled and stroked shapes with a gradient, the opacity
was applied during the composition and during the ctable update.
To prevent this, in case the composition occured, ctable
is updated with the opacity = 255.
* svg_loader: image tag: force size equal to the viewbox
For some svg files it is needed to force size equal the viewbox
for proper scaling
* svg_loader: image tag: force size equal to the viewbox fix#1
Duplicate declaration of id attribute is invaild.
We do not have a separate policy for invalid svg files.
Therefore, it is a priority to prevent crashes or memory leaks.
If an id is declared as duplicate, the last declared id is used.
If the copied data in JpgLoader's data open is invalid,
it is processed without being cleared.
Therefore, data memory free is handled in the destructor.
This patch introduces embeded <image> tag for svg files.
Images can be now loaded from local path or using data URI Scheme (RFC2397).
Base64 and utf8/uri are welcome.
