Function captureTables

captureTables(
bytes: Uint8Array,
options?: CaptureOptions,
): Promise<CapturedFace[]>
Reads a font file and captures the measures tables of each face in it: what SheetXL measures text with when the font itself is not at hand.
Parameters
- bytes: Uint8Array
  The font file.
- Optionaloptions: CaptureOptions
Returns Promise<CapturedFace[]>
One entry per face, in file order, less those CaptureOptions.filter declined.
Remarks
The tables are facts about the font's design (its advances and metrics), never its outlines, so they can go where the font itself cannot. Placed in a fonts resource root, they are found the next time a style names the family. This is what sheetxl fonts add does.

Accepts .ttf, .otf, and the collections .ttc and .otc.

Throws
when the bytes are not a font.
Example
```
for (const face of await IFont.captureTables(bytes)) {
  await writeFile(`${face.fileStem}.metrics.json`, face.metrics);
  if (face.hinted) await writeFile(`${face.fileStem}.hinted.json`, face.hinted);
}
```
