Release abell-v1.0.0-alpha.67: Explicit Declaration Block and some Bug Fixes · abelljs/abell

What's Changed

Explicit Declarations
```
{{
  // declarations
  const a = 3;
}}
<html>
  <body>{{ a }}</body>
</html>
```
You can now explicitly declare first block as declaration block without having import in it. Earlier the first block was considered declaration only if it had import mentions.
fix: abell's default routing file resolution logic
Add documentation to NPM
NPM has the README file now- https://www.npmjs.com/package/abell/v/1.0.0-alpha.67
New command abell clear-cache is added to clear cache
Currently cache is versioned so haven't seen a usecase but few edge cases might come up in future
Output File Path Pattern is configurable now (Untested Feature)
More details on this in future releases. Some internal changes were made for upcoming feature release
