Feature Request: support accessing array elements

[mahendraHegde]

Currently there is no way to access array elements
ex:

const tpl = require('nano-var-template')()
console.log(tpl("Hello {users[0].name}!", {users:[{name: "Jane Doe"}]}))

Proposal

1. support accessing all elements of array using a delimiter(ex: $) as index, concat multiple items with \n or with a configurable option

console.log(tpl("Hello {users[$].name}!", {users:[{name: "Jane Doe"},{name: "John Doe"}]}))
// Hello Jane Done \n John Doe

2. support accessing specific elements of array

console.log(tpl("Hello {users[1].name}!", {users:[{name: "Jane Doe"},{name: "John Doe"}]}))
// Hello John Doe
