Add support for F1:1 images, and in general with any framerate ratio.
Also added "F60:1" mode support.
Tested:
Added a test frame with a 1:1 framerate. This is produced by ffmpeg when
converting from another image format.
```
$ ffmpeg -i in.265 out.y4m
$ head -1 out.y4m
YUV4MPEG2 W490 H490 F1:1 Ip A0:0 C420jpeg XYSCSS=420JPEG XCOLORRANGE=FULL
```
Before
```
$ imlib2_view -v ./test/images/icon-64.framerate_1_1.y4m
Show 0: './test/images/icon-64.framerate_1_1.y4m'
*** Error -2:'Imlib2: No loader for file format' loading image: './test/images/icon-64.framerate_1_1.y4m'
```
After:
