* fix: update module github.com/googleapis/go-sql-spanner to v1.18.1 (#540)

* chore: add .NET gRPC wrapper

Adds a gRPC wrapper for .NET. This wrapper uses the gRPC API to connect to SpannerLib.
The gRPC channel uses a Unix domain socket.

* fix: update dependency net.java.dev.jna:jna to v5.18.1 (#544)

* chore: store temp TransactionOptions in connection state (#548)

Store temporary TransactionOptions in the connection state as local options. Local options
only apply to the current transaction. This simplifies the internal state handling of the
driver, as all transaction state should only be read from the connection state, and not
also from a temporary variable.

This also enables the use of a combination of temporary transaction options and using
SQL statements to set further options. The shared library always includes temporary
transaction options, as the BeginTransaction function accepts TransactionOptions as an
input argument. This meant that using SQL statements to set further transaction options
was not supported through the shared library.

* feat: parse SET TRANSACTION statements (#549)

* feat: parse SET TRANSACTION statements

Parse SET TRANSACTION statements and translate these to SET LOCAL statements.
SET TRANSACTION may only be executed in a transaction block, and can only be
used for a specific, limited set of connection properties. The syntax is
specified by the SQL standard and PostgreSQL.

See also https://www.postgresql.org/docs/current/sql-set-transaction.html

This change only adds partial support. The following features will be added
in future changes:
1. SET TRANSACTION READ {WRITE | ONLY} is not picked up by the driver, as
   the type of transaction is set directly when BeginTx is called. A
   refactor of this transaction handling is needed to be able to pick up
   SET TRANSACTION READ ONLY / SET TRANSACTION READ WRITE statements that
   are executed after BeginTx has been called.
2. PostgreSQL allows multiple transaction modes to be set in a single
   SET TRANSACTION statement. E.g. the following is allowed:
   SET TRANSACTION READ WRITE, ISOLATION LEVEL SERIALIZABLE
   The current implementation only supports one transaction mode per
   SET statement.

* feat: support multiple transaction options in one statement

* feat: support transaction options in BEGIN statements

Adds support for including transaction options in BEGIN statements, like:

```sql
BEGIN READ ONLY;
BEGIN READ WRITE;
BEGIN TRANSACTION ISOLATION LEVEL REPEATABLE READ;
BEGIN READ WRITE, ISOLATION LEVEL SERIALIZABLE;
```

* chore: re-trigger checks

* chore: add timeout for server startup
