### Describe the usage question you have. Please include as many useful
details as possible.
In the javascript package, how could one deserialize an Arrow schema from
raw bytes?
In pyarrow, for example, I can do this:
```python
import pyarrow as pa
import io
import base64
pa.ipc.read_schema(io.BytesIO(base64.b64decode(b'/////3AAAAAQAAAAAAAKAAwABgAFAAgACgAAAAABBAAMAAAACAAIAAAABAAIAAAABAAAAAEAAAAUAAAAEAAUAAgABgAHAAwAAAAQABAAAAAAAAEDEAAAABgAAAAEAAAAAAAAAAEAAAB4AAYACAAGAAYAAAAAAAEA')))
```
But I'm struggling to find any way to do the equivalent in javascript, even
after reading the code a bit.
The below (and various permutations involving ArrayBuffers, ByteBuffer
objects in flatbuffers, etc.) all fail.
```javascript
import { Message, Schema, tableFromIPC } from 'apache-arrow'
const sch =
`/////3AAAAAQAAAAAAAKAAwABgAFAAgACgAAAAABBAAMAAAACAAIAAAABAAIAAAABAAAAAEAAAAUAAAAEAAUAAgABgAHAAwAAAAQABAAAAAAAAEDEAAAABgAAAAEAAAAAAAAAAEAAAB4AAYACAAGAAYAAAAAAAEA`
const decoded = atob(sch);
const bytes = Uint8Array.from(decoded, c => c.charCodeAt(0))
console.log(Schema.decode(bytes))
```
I can deserialize a full table with tableFromIPC, but there are times that I
would like to work with a schema without any attached data.
Thanks for any help!
