feat: suport compressed files

[RodrigoDornelles]

allow decompressing, as this serves both to load game roms and fonts from other sites.

I'm trying to use DecompressionStream but I still don't understand how to use the API.

• https://developer.mozilla.org/en-US/docs/Web/API/DecompressionStream

export function isDeflate(fileContent: string): boolean {
    return fileContent.slice(0, 2) == 'PK'
}

export async function fileFromDeflate(fileContent: string): Promise<string> {
    const zipData = Uint8Array.from(fileContent, (c) => c.charCodeAt(0));
    console.log(zipData)

    // @ts-ignore
    const decompressionStream = new DecompressionStream('deflate');

    const response = new Response(zipData);
    console.log(response)

    // @ts-ignore
    const unzippedStream = response.body.pipeThrough(decompressionStream);
    
    const unzippedText = await new Response(unzippedStream).blob();
    return unzippedText.text(); 
}

async function read() {
        const filelist: FileList = fileInput.files as FileList
        contentBin = await readFile(filelist[0])
        contentBin = isDeflate(contentBin)
            ? await fileFromDeflate(contentBin)
            : contentBin
        contentChr = isRom(contentBin)
            ? chrFromRom(contentBin, parseInt(bankSelect.value))
            : chrFromPageChr(contentBin, parseInt(bankSelect.value))
}
