Refine import - Githubissues

What? Refine import syntax for

Decouple declare native function from import.

Update

Import Cases

import from local tbs file
```
import {func,class,var} from "./local/module"
```
.tbs will automatically append to import from file
import from javascript built-ins
```
import {Math} from "javascript"
```
special tbs file where all javascript methods declared. it should be outside library source.
import from compiled wasm binary
```
import {func,global_var,memory} from "./bin/module.wasm"
```
unwanted functions from imported wasm should be removed and combine in to one wasm output.

Notes: All declare syntax outside library source should allocate imports. import from wasm binary need a wasm binary parser.

if library && declare ---> no import if declare ---> import
