Fixed

• Fixed EPG sources that emit a UTF-8 BOM (e.g. ErsatzTV, EPGShare, WebGrab+Plus) parsing 0 channels and 0 programmes after the HTML entity fix introduced in v0.22.0. bytes.lstrip() only strips ASCII whitespace, leaving the three BOM bytes (EF BB BF) in place, so stripped.startswith(b'<?xml') returned False. The function fell through to the no-declaration branch and prepended the HTML entity DOCTYPE block before the BOM and XML declaration, producing invalid XML that lxml silently discarded under recover=True. Fixed by stripping the BOM explicitly before the whitespace strip: start.lstrip(b'\xef\xbb\xbf').lstrip(). BOM-free files are unaffected. (Closes #​1173) — Thanks @​dwot for the fix!
