Enhancement: Implemented a new --level command-line option that allows filtering of 'information' and 'warning' diagnostics.

Enhancement: Updated TOML parser to one that is compliant with the TOML 1.0 spec.

Enhancement: Added logic to detect uses of PEP 604 | syntax that generate exceptions due to runtime limitations. In particular, if one of the operands is a string (i.e. a forward reference) and the other is also a string or a class that is not explicitly specialized, this will result in an exception.

Bug Fix: Fixed recent regression in completion provider that resulted in garbled type information for a symbol that is declared as a function (using a def statement) but transformed into a non-function type using a decorator.

Bug Fix: Fixed a bug that resulted in a false positive error when an index expression with a numeric literal subscript was used in a loop that included a del statement targeting the same index expression.

Behavior Change: Modified the overload matching algorithm to match the behavior of mypy when the overload match is ambiguous because an argument evaluates to Any or Unknown. In this case, the call expression evaluates to Unknown. Previously, pyright used the first of the matching overloads in this case.

Bug Fix: Fixed a bug that led to extremely long type analysis times when determining type compatibility between an recursive type alias and a recursive protocol.

Bug Fix (contribution from @parched): Fixed recent regression that caused reportImportCycles diagnostic reporting to no longer work.

Bug Fix: Fixed a bug that resulted in a false positive error when a property setter or deleter contained function-scoped type variables.
