Oats can't handle query parameters defined with a hyphen `-`

Nobody has claimed this yet.

The following error is printed when trying to generate code from the attached swagger.

```sh
# yarn run oats oats/hyphen.yaml > hyphen.ts
(node:47395) UnhandledPromiseRejectionWarning: SyntaxError: Property or signature expected. (109:3)
107 |
108 | query?: {
> 109 | stuff-filter?: string;
| ^

**oats/hyphen.yaml**
```yaml
openapi: "3.0.0"
info:
title: Stuff service
version: 0.0.0
servers:
- url: /api/v2
paths:
/stuff:
get:
operationId: getStuff
parameters:
- $ref: "#/components/parameters/StuffFilter"
responses:
'204':
$ref: "#/components/responses/NoContent"
components:
parameters:
StuffFilter:
in: query
name: stuff-filter
required: false
description: stuff to return
schema:
type: string
responses:
NoContent:
description: No content
```

Word on the street is that something like this works fine, maybe if the names are quoted to avoid this error:
```ts
const foo = {
'stuff-filter': 'some filter'
}
```

Reproduce the failure with oats/hyphen.yaml using the documented yarn run oats oats/hyphen.yaml > hyphen.ts command, then inspect the generated TypeScript around the query parameter. The fix is complete when the hyphenated parameter produces valid TypeScript with the original query name preserved and the generator no longer fails during formatting.
