Fix Ajv import

[ledleds]

Thanks for this package! I had trouble finding something to help me validate and OpenApi Doc with nested discriminators but I managed to get this working for my needs and its great!

Opening this PR to fix this issue that cropped up for me, ajv is the default export:

node_modules/express-json-validator-middleware/src/index.d.ts:4:10 - error TS2614: Module '"ajv"' has no exported member 'Ajv'. Did you mean to use 'import Ajv from "ajv"' instead?

4 import { Ajv, ErrorObject, Options as AjvOptions } from "ajv";
           ~~~


Found 1 error.

@ledleds Thanks so much for this fix! I'm going to open a separate PR to automatically type check these type definitions.

I'm surprised this issue hasn't cropped up before. I can only guess that most folk have skipLibCheck enabled in their tsconfig.json.

Released in v3.0.1 (npm).
