Possible bug in uid/gid value

[casatir]

Environment

Typescript, Webpack, Browser.

Reproduction

tar -cpf home.tar ~/
tar --numeric-owner -tvf home.tar

console.log(parseTar(home));

Describe the bug

According to https://www.gnu.org/software/tar/manual/html_node/Standard.html, uid and gid are octal numbers encoded in ASCII.

nanotar/src/parse.ts

Line 57 in 4fe65ab

const uid = Number.parseInt(_readString(buffer, offset + 108, 8));

Shouldn't it be

const uid = _readNumber(buffer, offset + 108, 8);

? Same for gid ?

A tar file created using GNU tar shows 1001/1001 with tar --numeric-owner -tvf and 1751/1751 with nanotar (0o1751 === 1001).
