### What problem does this PR solve?
## Problem
When parsing PDFs containing English figure/table captions (e.g. "Fig.
20", "Figure 20", "Table 20"), the `is_caption` method in
`TableStructureRecognizer` failed to recognize them as captions. This
caused figure numbering gaps in the parsed output (e.g. Fig. 19 → Fig.
21, skipping Fig. 20).
## Root Cause
The `is_caption` regex only matched Chinese caption formats:
```python
patt = [r"[图表]+[ 0-9:：]{2,}"]
```
When the layout recognizer also failed to assign a `caption` layout type
to a given text block, English captions were entirely missed.
## Fix
Added three case-insensitive English caption patterns to `is_caption` in
`deepdoc/vision/table_structure_recognizer.py`:
- `(?i)Fig\.?\s*\d+` — matches `Fig. 20`, `Fig 20`, `FIG. 20`, etc.
- `(?i)Figure\s+\d+` — matches `Figure 20`, `FIGURE 20`, etc.
- `(?i)Table\s+\d+` — matches `Table 20`, `TABLE 20`, etc.
## Files Changed
- `deepdoc/vision/table_structure_recognizer.py` — extended `is_caption`
regex patterns
- [x] Bug Fix (non-breaking change which fixes an issue)
