Support secp256k1, secp384r1, secp521r1 elliptic curve key conversion  
Can be converted from rawKey to hexadecimal DER format and PEM format


Currently only supports secp384r1
Usage:
```
var keyConversion = require('key-conversion');
let rawPub = '04....';
let pubType = 'secp384r1'; //'secp384r1' or'secp521r1'
let pubDER = keyConversion.convertPublicKeyToDer(pubType, rawPub);
var pubPEM = keyConversion.convertPublicKeyToPem(pubType, rawPub);


let rawPrivate = 'e7...';
let privateType = 'secp384r1'; //'secp384r1' or'secp521r1'
let privateDER = keyConversion.convertPrivateKeyToDer(privateType, rawPrivate);
var privatePEM = keyConversion.convertPrivateKeyToPem(privateType, rawPrivate);


```
