GitHub has specified FUNDING.yml, a file to include in a git repo for
pointing people to donation links. Since F-Droid also points people
to donation links, this parses them to fill out Donate:
and OpenCollective:. Specifying those in the metadata file takes
precedence over the FUNDING.yml. This follows the same pattern as how
`fdroid update` includes Fastlane/Triple-T metadata. This lets the
git repo maintain those specific donations links themselves.

The test file was generated using:
```python
import os, re, yaml
found = dict()
for root, dirs, files in os.walk('.'):
for f in files:
if f == 'FUNDING.yml':
with open(os.path.join(root, f)) as fp:
data = yaml.safe_load(fp)
for k, v in data.items():
if k not in found:
found[k] = set()
if not v:
continue
if isinstance(v, list):
for i in v:
found[k].add(i)
else:
found[k].add(v)
with open('gather-funding-names.yaml', 'w') as fp:
output = dict()
for k, v in found.items():
output[k] = sorted(v)
yaml.dump(output, fp, default_flow_style=False)
```
