Function retry

retry<T>(fn: () => Promise<T>, opts?: RetryOptions): Promise<T>
Runs fn, retrying it with exponential backoff while it throws a retryable error.

The delay before retry n (0-based) is min(maxMs, baseMs * 2 ** n), optionally with full jitter. A non-retryable error (per RetryOptions.retryable) is rethrown immediately, as is the last error once attempts is exhausted.
Type Parameters
- T
  The resolved value of fn.
Parameters
- fn: () => Promise<T>
  The operation to run; typically a connect or a one-shot request.
- opts: RetryOptions = {}
  Attempt count, backoff timing, jitter, and the retryable predicate.
Returns Promise<T>
Whatever fn resolves to.
Throws
The last error fn threw, once attempts are exhausted or the error is not retryable.

1.0.3
Example
```
import { retry } from 'edgeport/util';
import { connect } from 'edgeport/ssh';

// retry the connect up to 4 times on transient network errors; a bad password fails at once
const ssh = await retry(() => connect({ hostname: 'box', username: 'u', password: pw }), {
	attempts: 4
});
```
